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.

The second near-infrared window (NIR-II, 1000–2000 nm) provides an ideal window for multichannel photoluminescence lifetime imaging (mPLI) because of its exceptional tissue penetration depth and minimal scattering. However, the inevitable spectral crosstalk that is caused by the broad and overlapping emissions of traditional luminescent materials (e.g., organic dyes and quantum dots) has restricted the scalability of mPLI channels. Herein, we developed a series of Ln 3+ -doped (Ln = Nd, Er, Tm, or Ho) stratified nanoparticles (Ln-SNPs) that enable highly efficient multiwavelength NIR-II luminescence. These nanoparticles can be further engineered into concentration-mediated Yb 3+ energy relay nanoparticles to enable the precise tuning of the luminescence lifetime across the 1060–2050 nm range, thereby expanding the NIR-II imaging channels in mPLI. Notably, the engineered Tm-SNPs exhibit optimized downshifting emission at ∼1850 nm (NIR-IIc subwindow) with distinguishable luminescence lifetimes that span three orders of magnitude at similar emission intensities. This advancement establishes a powerful toolkit for multidimensional information encryption and multiplexed bioimaging applications.

All-inorganic perovskite quantum dots (QDs) (CsPbX 3 , X = Cl, Br, I) have shown great promise in optoelectronic applications but are severely hindered by their poor environmental stability and photoluminescence (PL) quenching. In this work, we report a novel approach for enhancing both stability and optical performance by insitu growth of CsPbBr 3 QDs within a borosilicate glass matrix, assisted by SrF 2 and Sm 2 O 3 codoping. The introduction of F − ions from SrF 2 modifies the glass network structure, promoting uniform nucleation and growth of QDs. Simultaneously, Sm 3+ doping, through partial incorporation into the CsPbBr 3 QD lattice, passivates surface defects and induces lattice contraction, which enhances quantum confinement effects. At the optimal Sm 3+ concentration of 1 mol%, the PL intensity increases by 332.8%, the photoluminescence quantum yield rises from 22.01% to 37.5%, and the fluorescence lifetime extends from 95.05 to 127.69 ns. The glass encapsulation provides long-term air and water stability, outperforming conventional ligand-capped QDs. Moreover, the developed materials were successfully applied in high-brightness green and white light-emitting diodes, achieving wide color gamut coverage (up to 129.4% NTSC), and demonstrated strong potential in forensic fingerprint visualization. These results provide a new pathway for developing stable, multifunctional perovskite-based optoelectronic materials. Graphical This study demonstrates a dual strategy of F − /Sm³ + codoping and glass encapsulation to significantly enhance the luminescence performance and stability of CsPbBr 3 quantum dots. Optimal Sm³ + doping (1 mol%) yields a 332.8% increase in photoluminescence intensity, improves quantum efficiency from 22% to 37.5%, and extends fluorescence lifetime to 127.69 ns. The glass matrix provides exceptional environmental stability, retaining 78.65% initial luminescence after 50 days in air. Resulting light-emitting diode devices achieve a wide color gamut covering 129.4% of the NTSC standard.

Colorectal cancer (CRC) remains a leading cause of cancer-related mortality worldwide, with limited efficacy of conventional therapies due to immunosuppressive tumor microenvironments and high recurrence. While bispecific T-cell engagers (BiTEs) show promise by engaging T cells against tumors, their clinical translation is hindered by poor stability, on-target off-tumor effect, and systemic toxicity. Herein, we develop a tumor-targeted nanozyme (MnO 2 -dsDNA@BiTE/APT) that co-delivers hydrolytically stable double-strand DNA (dsDNA: a STING agonist) and PD-L1/CD3 BiTE to overcome these limitations. The nanozyme leverages MnO 2 as a carrier for dsDNA, surface-loaded with BiTE via polyphenol-protein coordination, and functionalized with an aptamer (APT) for active targeting. Upon systemic administration, the nanozyme accumulates in tumors, releasing dsDNA, Mn 2+ , and BiTE. The synergistically activates the STING pathway to remodel the immunosuppressive microenvironment and enhances T cell-mediated cytotoxicity. This strategy represents a promising approach for potentiating immunotherapy in CRC by integrating innate immune activation with adaptive T cell engagement.

Parkinson's disease (PD) is a progressive neurodegenerative disorder with incompletely understood pathophysiology, necessitating advanced tools for long-term dynamic biomarker monitoring. Current techniques lack noninvasive platforms capable of real-time multiparametric monitoring with high stability, sensitivity, and responsiveness. Here, we engineered core-shell-shell lanthanide-doped upconversion nanoparticles (cssUCNPs) through controlled Tm 3+ /Er 3+ gradient doping and crystal field symmetry modulation. This “sandwich” heterostructure design suppressed cross-relaxation, while Ca 2+ doping enhanced radiative transition efficiency. These modifications yielded a quantum yield improvement from 0.35 ± 0.014% to 3.27 ± 0.067%, representing a 9.3-fold enhancement, alongside a fluorescence intensity increase of 425.5-fold. The cssUCNPs exhibited exceptional photostability (>10,000 excitation cycles) and biocompatibility (>95% cell viability). Upon integration of Fluo4 with UCNPs, the system harnessed the luminescence resonance energy transfer effect to enable dual-responsive sensing of Ca 2+ (detection limit: 1 μM) and temperature (sensitivity: 0.5 K −1 ), thereby facilitating long-term tracing of Ca 2+ and temperature dynamics across PD pathological stages. Our results revealed that early-phase PD is characterized by rapid Ca 2+ and temperature surges, followed by oscillatory fluctuations in the middle phase, and eventual stabilization at elevated levels in the terminal phase. These dynamic profiles establish a direct link between mitochondrial dysfunction and Ca 2+ dysregulation, highlighting Ca 2+ flow-sensitive and thermally sensitive therapeutic targets for PD intervention.

The increasing demand for high-speed X-ray imaging requires scintillators with high light yield and fast response. Perovskite nanocrystals are promising candidates due to their distinctive optical properties and solution processability. However, the fabrication of thick X-ray films, which are several orders of magnitude thicker than conventional optoelectronic devices, leads to severe material waste and reduced light yield caused by strong spectral overlap and self-absorption. In addition, conventional synthesis methods often suffer from low reaction yields and uncontrolled exciton pathways. Here, we develop a low-temperature polar-solvent synthesis method that achieves a reaction yield of 162 mg mL −1 and optimizes exciton routing for improved energy transfer. This approach increases the Stokes shift and reduces the radioluminescence decay to 7.19 ns. Consequently, high-speed X-ray imaging at 7,680 frames per second with a spatial resolution of 27.6 line-pairs per millimeter is achieved, supporting sustainable commercialization of perovskite nanocrystal scintillators for dynamic X-ray imaging.

The growing demand for petroleum has intensified the pressure on conventional resources, driving exploration into unconventional reservoirs. Polyacrylamide (PAM) emulsion drag reducers can suppress fracturing fluid turbulence and improve reservoir stimulation, but their poor dissolution efficiency remains a key obstacle to widespread application. Herein, a pH-responsive Gemini surfactant (PA/OA) featuring a rigid piperazine ring as the hydrophilic headgroup was synthesized using piperazine (PA) and oleic acid (HOA). The PA/OA-stabilized monomer emulsion exhibited excellent stability for over 50 days at pH 7.0, enabling the successful inverse emulsion polymerization of PAM. The introduction of the piperazine ring and double hydrophobic tails enhances the molecular rigidity to promote a tight arrangement at the oil–water interface, thereby reinforcing the interfacial film and enhancing the interfacial activity. The surface activity of PA/OA varied at different pH conditions due to the interionic proton transfer between OA and PA. The pH-responsive ionic bonds in PA/OA facilitate rapid release of emulsion drag reducers, with most released within 30 s at pH = 10.0, and achieve a drag reduction rate of 68% at a concentration of 0.05 wt %. The PA/OA-stabilized emulsion effectively reconciled the conflict between long-term storage stability and rapid release performance encountered in single-chain-responsive surfactant systems.

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.

A facile and novel bilayer HTL is demonstrated to enhance the performance of PbS QDs photovoltaics. • The advanced bilayer HTL shows “crack-healing” effect while maintains well -matched energy levels with photoactive layer. • The advanced bilayer HTL exhibits remarkably suppressed trap states and high film quality. • As results, high-performance narrowed-bandgap PbS QDs IR cells are achieved with a champion IR PCE of 1.52%. PbS quantum dots (QDs) infrared (IR) solar cells, able to convert low-energy IR photons into electron-hole pairs, are hopeful photovoltaic devices because it broadens the utilization range of the solar spectrum to IR region. Currently, PbS infrared solar cells usually apply small-sized PbS QDs treated with 1,2-ethanedithiol as hole transport layer (HTL) by solid-state ligand exchange (SSLE) method. However, cracks are prone to generate in HTL due to volume shrinkage in SSLE process, resulting in deterioration of devices performance. Here, a facile and novel bilayer PbS QDs HTL is demonstrated by applying QDs synthesized via different methods to form bilayer structures. It is discovered that bilayer structure can “healing” the film cracks and reduce trap states, which is contributed to the carrier separation and extraction in devices. Meanwhile, the advanced bilayer HTL maintains the well-match energy levels with the narrowed-bandgap PbS QDs photoactive layer. As results, superior average AM1.5 PCE of 10.45% (the champion device achieved 12.27%) and average infrared PCE (IR PCE) of 1.24% (the champion device achieved 1.52%) were obtained in devices with the bilayer HTL, demonstrating a facile and reliable approach to enhance the performance of optoelectronic devices. A facile and novel bilayer HTL is demonstrated to improve device performance. Download: Download high-res image (338KB) Download: Download full-size image

A straightforward and highly selective upconversion luminescence (UCL) nanosensor was designed for the detection of cyanazine (CZ) pesticide residues in food and environmental samples, based on the luminescence resonance energy transfer (LRET) mechanism. Without any modification, the LRET system employed upconversion nanoparticles (UCNPs) and gold nanoparticles (AuNPs) as the energy donor and acceptor respectively to achieve efficient quenching of UCL. CZ specifically induced the aggregation and detachment of AuNPs from UCNPs, leading to the termination of LRET and achieving the “off-on” process of UCL. According to the changes in UCL, the linear range of the nanosensor for CZ detection was 0.1–8.0 μM, with a detection limit of 0.098 μM. Finally, the nanosensor was successfully applied to detect CZ spiked in lake water, tap water, and corn. The recovery rates were in the range of 98.99–101.42%, and the relative standard deviations (RSD) were below 3%. The proposed nanosensor exhibits excellent application prospects in complex sample matrices.

Selective deoxygenation of fatty acids to diesel-range alkanes without carbon-chain shortening is essential for sustainable biomass upgrading, but high selectivity remains challenging by competing decarbonylation/decarboxylation pathways. Here, a Re/In 2 O 3 featuring Re single atoms and ReO 3 clusters was synthesized for the hydrodeoxygenation of stearic acid. In contrast to In 2 O 3 , which primarily yields 1-octadecanol (93.1% selectivity) with minimal n-octadecane (1.2% selectivity), the optimized Re/In 2 O 3 catalyst achieves 100% selectivity diesel-range alkanes (>85% n-octadecane). Isotopic labeling, in situ spectroscopy, and kinetic analyses reveal Re-induced synergy: ReO 3 enhance H 2 dissociation, while Re single atoms promote bidentate adsorption of fatty acids, and oxygen vacancies in In 2 O 3 facilitate selective C–O bond cleavage. This multifunctional synergy suppresses C–C bond scission and significantly lowers the apparent activation energy for hydrodeoxygenation by 36.5 kJ·mol −1 . The catalyst exhibits broad applicability across diverse carboxylic acids, including unsaturated and aromatic substrates, underscoring its potential for efficient biomass utilization.

Scintillators for X-ray imaging have gained significant interest due to their essential roles in medical diagnostics, security screening, and industrial inspection. However, conventional scintillators often suffer from limitations, such as a low light output efficiency or poor stability. Herein, we report a novel bilayer scintillator based on copper halide nanocrystals, comprising Cs3Cu2Cl5/Cs3Cu2I5 nanocrystals, which exhibits better performance in X-ray imaging. By optimization of the copper halide nanocrystal passivated with ammonium halides, the photoluminescence quantum yield can be increased from 41.85 to 66.18%, facilitating the performance of these bilayer copper-based halide scintillators. It utilizes energy-dependent attenuation contrast generated through differential X-ray absorption in the bilayer copper-based halide scintillators to generate dual-energy X-ray imaging. Moreover, the all-inorganic composition ensures the exceptional stability of the scintillator under prolonged X-ray irradiation. This study presents an innovative approach for developing next-generation, high-performance, and cost-effective X-ray imaging scintillators.
