Nanoplastics are a significant environmental threat due to their persistence and toxicity. In this study, we prepared a kind of Ag-doped Co 3 O 4 catalyst using a coprecipitation method, aimed at enhancing its photocatalytic degradation efficiency of polystyrene nanoplastics under UV irradiation. Morphology and component of Ag/Co 3 O 4 have been investigated by XRD, FTIR, TEM, and BET analysis. The information of absorption and energy levels for catalysts is provided by UV–vis DRS, Tauc plots, and Mott–Schottky curves. Charge-transfer abilities for catalysts have been analyzed by PL spectra and EIS. The photocatalytic activities of Ag nanoparticles (Ag NPs), Co 3 O 4 , and Ag/Co 3 O 4 have been carefully evaluated in this work. Ag/Co 3 O 4 photocatalyst exhibits the highest degradation efficiency with a kinetic rate constant of 0.0086 min − 1 , outperforming that of Co 3 O 4 (0.0062 min − 1 ) and Ag NPs (0.0036 min − 1 ). The degradation efficiencies for catalysts have also been assessed under varying pH conditions (neutral, acidic, and basic). Among them, Ag/Co 3 O 4 shows a notable degradation efficiency of 61% at pH 7, compared to 46% for Co 3 O 4 and 30% for Ag NPs. In addition, the intermediates and final products have also been discussed according to Py-GC/MS results.

Fast-responsive and efficient perovskite QD-based light-emitting diodes (QLEDs) demonstrate significant potential in high refresh rate display applications. However, the response time and external quantum efficiency (EQE) remain limited by imperfect device architectures, including low carrier mobility in transport layers and severe interface losses. Here, we utilized a molecule (3-(6-(3-(4,6-di([1,1′-biphenyl]-4-yl)-1,3,5-triazin-2-yl)phenyl)pyridin-2-yl)phenyl) diphenylphosphine oxide (ETL-PO) as an electron transport layer (ETL) due to its high electron mobility, which could also reduce defects at the interface between the QDs and ETL in the perovskite QLED. The P═O group of ETL-PO coordinates with undercoordinated Pb 2+ to suppress nonradiative interfacial recombination, while the conjugated backbone supports efficient electron transport and reduces the device's resistance and capacitance. Resultantly, the QLEDs based on ETL-PO exhibit a total response time of 564 ns at an active area of 0.01 mm 2 , which is more than 50 times faster than that of 29 µs for control devices. Furthermore, a peak EQE of 22.8% with a maximum luminance of 105518 cd m −2 is reached. This work shows a perovskite QLED device successfully achieved both high EQE and nanosecond-level response time, providing a new perspective for the field of optical communication and data transmission.

Red perovskite quantum dots are critical for the next generation of micro-LED displays, yet their commercialization is thwarted by poor color purity and operational instability. Here, we report a novel, one-step fabrication of a flexible perovskite quantum dot nanopaper (PQDnP) that overcomes these challenges through a synergistic, multi-scale stabilization mechanism. We replace conventional surface ligands with a dual-component system: a sustainable cellulose nanocrystal matrix acts as a robust, thermally insulating scaffold, while a phenethylamine cation provides atomic-level surface passivation and induces the formation of a protective quasi-2D perovskite shell. This hierarchical design yields pure-red PQDnPs with a stable photoluminescence (PL) at 621 nm and a ultra-narrow spectral linewidth of less than 30 nm. The resulting nanopaper demonstrates outstanding robustness, including superior thermal stability and excellent photostability, retaining 74% of its PL intensity after 24 h under harsh blue-light irradiation (150 mW/cm 2 ). By integrating the PQDnP as a color converter with a vertically stacked blue/green μ-LED array, we demonstrate a white-light device with a high system external quantum efficiency of 4.5% and a high peak luminance of over 26,000 cd/m 2 . This bio-inspired, scalable approach provides a practical solution to the persistent “red gap” problem, paving the way for high-fidelity perovskite-based micro-displays.

The inherent nonlinearity and limited multimodal sensing capabilities of conventional flexible sensors hinder their applications in complex scenarios such as wearable health monitoring and human-machine interaction. Here, a fully solid-state sensor based on MXene/silk fibroin (SF) composite membrane is proposed, which features expanded interlayer spacing and enhanced mechanical strength, achieving a linear and self-powered conversion of both pressure- and light-driven ionic conversion to electrical responses. In force-electric conversion mode, the current and voltage sensitivity of the obtained pressure sensor with solid electrolyte can reach 2.667 mA m −2 kPa −1 and 0.083 mV kPa −1 , respectively. In light-electric conversion mode, the switching ratio of current is as high as 2658.0, and the response time is as fast as 25 ms. The dual-mode synergy was successfully applied to wearable physiological monitoring, acoustic wave recognition, image recognition, and information encryption, establishing a new paradigm for next-generation bionic sensing systems.

White light-emitting diodes (WLEDs) play a crucial role in solid-state lighting technologies. Among the key factors contributing to their performance, the development of high-quality cyan phosphors is critical in achieving excellent color rendering index (CRI) and stable long-term operation. In this study, a cyan-emitting phosphor, NaBa 2 Al(P 2 O 7 ) 2 : x Eu 2+ ( x = 0.01-0.06), was explored. The material's structures, morphology, optical behavior, and thermal stability were analyzed. Rietveld refinement reveals that the phosphor exhibits high crystallinity and confirms the successful substitution of Eu 2+ ions into Ba 2+ sites within the crystal lattice. Upon excitation at 320 nm, the phosphor emits broad, asymmetric cyan light, with peak intensity occurring at an Eu 2+ concentration of 0.03 achieving internal quantum efficiency (IQE) of 68.9%. Energy transfer and Gaussian fitting analyses show that Eu 2+ ions occupy two distinct crystallographic sites, and concentration quenching is attributed to dipole-dipole interactions. The phosphor retains 77% of its intensity at 425 K, with an activation energy of 0.3173 eV, demonstrating high thermal stability and color consistency. When integrated with a red-emitting phosphor onto a 320 nm UV chip, a white light-emitting diode (WLED) is fabricated, exhibiting a correlated color temperature (CCT) of 5727 K and a color rendering index (CRI) of 95.6. These results highlight this phosphor for applications in advanced white light-emitting diode (WLED) technologies across diverse lighting systems.

Oxygen migration on catalyst surfaces is crucial for transforming two greenhouse gases (CH 4 and CO 2 ) into syngas through dry reforming of methane (DRM), as it drives key elementary reactions, generates reactive oxygen vacancies and suppresses carbon deposition. An efficient light-enhanced oxygen-migration strategy was successfully implemented with an Ir/CeO 2 photothermal catalyst in this work. Recordable photothermal catalytic production rates of 6.56 and 8.55 mol·g -1 ·h -1 for H 2 and CO have been achieved at 700 °C with a light intensity of 28 kW·m -2 . Compared with dark conditions, the yields of H 2 and CO under light exposure are increased by 106% and 57%, respectively, with the conversions of CH 4 and CO 2 reaching 50% and 64%. Furthermore, the pivotal role of the pronounced oxygen-migration-mediating capability of Ir clusters supported on CeO 2 has been unveiled by integrating theoretical calculations with a suite of in-situ characterizations. Photogenerated electrons transfer from CeO 2 to the Ir species, enhancing their ability to induce oxygen migration and generate oxygen vacancies, thereby leading to a significant increase in photothermal catalytic DRM performance. This work not only successfully developed an efficient photothermal catalyst for DRM but also proposed an innovative view to inspire the mechanism of light-enhanced catalysis based on oxygen migration.

Metal halide double perovskite Cs₂AgInCl₆, as an environmentally friendly direct-bandgap semiconductor, emerged as a strong candidate for a new generation of environmentally friendly and stable photocatalysts due to its long carrier lifetime, non-toxicity, and moisture resistance. However, due to parity-forbidden transitions and high sensitivity to water, achieving higher-efficiency photocatalytic degradation in water remained an urgent challenge. Our study presented for the first time a high-entropy Cs 2 AgInCl 6 material Cs₂(Na₁/₂Ag₁/₂)(Mn₁/₃In₁/₃Bi₁/₃)Cl₆ (ANIBM DPNCs), which exhibited a remarkable visible light responsive and applicable to degrade pollutants in aqueous environments. In comparison with existing photocatalysts within the halide perovskite family, ANIBM DPNCs has been shown to exhibit higher photocatalytic efficiency and to demonstrate low sensitivity to various environments such as water and oxygen. Within 30 min, the RhB (10 mg/L) was completely degraded, while demonstrating comprehensive phase stability. Following four cycles of reuse and four months of atmospheric exposure, ANIBM DPNCs exhibited no structural alteration and retained its original photocatalytic performance. Notably, at elevated temperatures of 483 K, a remarkable resilience was exhibited, with the material retaining its original crystal structure. The results demonstrated that this material can be efficiently synthesized, is non-toxic, and exhibited outstanding photocatalytic performance and stability. This advancement successfully overcame the limitations of Cs 2 AgInCl 6 in photocatalysis, which were previously restricted to ultraviolet response and degradation in ethanol solutions. Our research provided a solid foundation for the transformation of Cs 2 AgInCl 6 from a low-efficiency luminescent material into a high-performance photocatalyst.

Abstract The modulation of metal–support interaction (MSI) could provide exciting catalytic performance for the heterogeneous catalyst. Herein, we report a novel and fast strategy to controllably modulate the physicochemical structure of supports through NIR laser irradiation and then reconstruct the interface between the metal site and support. The abundant oxygen vacancies, tunable anatase-rutile phases, and unique surface properties of TiO2 supports can be formed by laser irradiation in 3 s. It is worth mentioning that the structure and properties of TiO2 supports can be controllably modulated by controlling the intensity of laser irradiation, thereby tuning the MSI between active Ru sites and TiO2 supports to promote the catalytic performance of Ru/TiO2 catalysts. Specifically, the optimized interfacial activity of the Ru/TiO2 catalyst would exhibit excellent electron/mass transfer, which facilitates the adsorption and activation of H-donor (alcohols) and ethyl levulinate (EL), thereby improving the EL catalytic transfer hydrogenation (CTH) to γ-valerolactone (GVL), achieving 95% GVL yield, 96% EL conversion, and 99.0% GVL selectivity under mild conditions (150 °C, 12 h, 2-PrOH as H-donor). This research provides an innovative approach for fast modulation of support to tune the MSI, thus enhancing the catalytic activity of catalysts.

Perovskite nanocrystals (NCs) have emerged as highly promising emitters for light-emitting diodes (LEDs) owing to their outstanding luminescence properties, broadly tunable band structures, and intrinsically high color purity. Surface ligand engineering plays a crucial role in regulating the electroluminescent performance and device stability of perovskite NCs. Here, we develop a cooperative 2-(4-(methylsulfonyl)phenyl)ethylamine (MSPE)-hydrogen halide (HX, X = Br, I) ligand-exchange strategy that enables surface reconfiguration and robust passivation of perovskite NCs. In this approach, HX assists in removing insulating long-chain ligands (oleic acid and oleylamine), thereby exposing additional undercoordinated surface sites and promoting firm double-end anchoring of in situ protonated MSPE through bidentate interactions. Spectroscopic and electrical analyses reveal that the strengthened ligand-nanocrystal interface effectively suppresses trap-assisted nonradiative recombination, increases the exciton binding energy from 97.7 to 168.9 meV, prolongs the lifetime from 9.5 to 12.3 ns, and reduces trap densities in CsPbBr3 NC films. As a result, the photoluminescence quantum yield of CsPbBr3 NCs after MSPE-HBr treatment is enhanced to 96.1%, and LEDs fabricated with MSPE-HBr-treated NCs deliver a peak external quantum efficiency of 25.2% and display excellent device-to-device reproducibility. This cooperative ligand-exchange strategy provides an effective pathway for achieving high surface coverage of robust multidentate ligands, offering a promising route toward highly efficient and stable perovskite LEDs.

A cost-effective CuGaS 2 /ZnS QD synthesis achieves ultrabroadband white emission with a FWHM of 257.9 nm and PLQY of 34.5%. • Cu/Ga ratio and coating temperature regulate defect trapping and carrier relaxation for tunable ultrabroadband emission. • QD-based pc-WLEDs deliver high-quality white light with CIE (0.348, 0.359), CRI of 94.9, CCT of 4915 K, and EQE of 23.8%. Colloidal I-III-VI QDs have emerged as promising candidates for environmentally benign next-generation illumination owing to their facile synthesis, low toxicity, and exceptional optoelectronic properties, yet achieving high-quality white-light emission remains challenging. Herein, we report a cost-effective and sustainable synthesis of CuGaS 2 /ZnS QDs exhibiting ultrabroadband white-light emission with a full width at half maximum (FWHM) of 257.9 nm and a robust photoluminescence quantum yield (PLQY) of 34.5%. Mechanistic investigations reveal that Cu/Ga compositional engineering regulates Cu vacancies, suppressing intrinsic nonradiative recombination while stabilizing shallow-defect-related high-energy emission. Concurrently, temperature-dependent shell growth may regulate interfacial cation redistribution and defect configurations, thereby modulating cation-disorder-associated localized STE-like states, contributing to long-lived low-energy emissions. Through the synergistic suppression of nonradiative recombination and modulation of carrier relaxation and trapping dynamics, the coating temperature redistributes carrier populations between intrinsic and defect-related states, enabling stable dual emission and highly tunable ultrabroadband emission across the entire visible spectrum. Furthermore, phosphor-converted white light-emitting diodes (pc-WLEDs) fabricated by integrating CuGaS 2 /ZnS QDs with red-emitting CuInS 2 /ZnS QDs deliver high-fidelity white-light emission with a color rendering index (CRI) of 94.9 and an external quantum efficiency of 23.8%, closely reproducing the spectral characteristics of natural sunlight and highlighting their promise for solid-state lighting and display technologies.

A series of Mn 4+ /Eu 3+ co-doped double-perovskite Sr 3 LiSbO 6 phosphors was successfully synthesized by the high-temperature solid-state method. The Sr 3 LiSbO 6 : Mn 4+ phosphor exhibits a broad far-red emission band centered at 693 nm, which is assigned to the 2 E g → 4 A 2g transition of Mn 4+ ions. The doping of Eu 3+ ions realizes the regulation of emission spectra, and the phosphors with red/far-red double-peak emission (611 and 693 nm) are obtained. The spectrum is suitable for plant lighting because of its good overlap with the absorption band of phytochrome P R and P FR . Notably, the presence of Eu 3+ enhances the emission intensity of Mn 4+ by 1.56 times due to the synergistic effect of charge compensation and local lattice tuning. These results indicate that Sr 3 LiSbO 6 : Mn 4+ /Eu 3+ phosphors are promising materials for applications in plant cultivation.

Natural photosensitizers are promising for postharvest fruit preservation, but their antibacterial efficacy is often limited by weak visible-light responsiveness. Based on the natural photosensitizer quercetin, this study prepared an Fe-quercetin coordination complex (QF), which was subsequently incorporated into an edible coating with a pectin matrix for the preservation of strawberries. DRS-Tauc analysis showed that iron coordination reduced the bandgap of quercetin from 2.64 eV to 1.86 eV, and EPR analysis confirmed the generation of 1 O 2 , •O 2 − , •OH, and HO 2 • under illumination. Under visible-light irradiation, QF completely inactivated Staphylococcus aureus at 0.2 mg/mL within 10 min and Escherichia coli at 0.3 mg/mL within 5 min, whereas free quercetin was markedly less effective under the same conditions. In strawberries stored at 25 °C for five days, the QF-P coating delayed spoilage, reducing weight loss from approximately 16.63% to approximately 7.95%, while maintaining a firmness of approximately 242 g. QF-P coating also better preserved the pH, total soluble solids and color of strawberries during storage. These results show that iron coordination is an effective way to improve the visible-light-driven antibacterial activity of quercetin and support the use of QF-based edible coatings for preserving perishable fruits under mild conditions.
