Reactive oxygen species (ROS)-mediated sterilization typically relies on continuous light irradiation or exogenous H 2 O 2 addition, limiting their practical utility under dark or resource-limited conditions. Herein, we rationally design an S-scheme MIL-100(Fe)/Zn 3 In 2 S 6 heterojunction (M 5 Z 1 –1@ZIS2) by in-situ growing Zn-doped MIL-100(Fe) on Zn 3 In 2 S 6 , achieving synergistic light-harvesting and ROS self-supply capabilities. The incorporation of Zn 3 In 2 S 6 enhances electron density around Fe 2+ sites while modulating Fe 3+ states, significantly improving O₂ activation and H 2 O 2 affinity. This unique electronic regulation enables the heterojunction to generate superoxide radical(·O₂ − )-dominated ROS even in the dark. Notably, visible-light pretreatment induces active In sites in Zn 3 In 2 S 6 to produce H 2 O 2 , which accumulates and sustains the FeII/FeIII redox cycle in the absence of light, driving continuous hydroxyl radical(·OH)-dominated ROS generation. Combined characterizations including X-ray photoelectron spectroscopy (XPS) and Electron Paramagnetic Resonance (EPR) confirm H₂O₂-mediated Fe 2+ regeneration and ROS persistence. The M 5 Z 1 –1@ZIS2 heterojunction exhibits exceptional antibacterial performance, achieving ≥99.9% inactivation of Escherichia coli ( E. coli ) within 1.5 h in the dark and 40 min under visible light. This work provides a strategy for designing self-sustaining catalytic systems that leverage light-driven H₂O₂ supply to enable day-night ROS functionality. Furthermore, M 5 Z 1 –1@ZIS2 loaded on polyvinylidene fluoride (PVDF) film can achieve an efficiency of over 99% for particulate matter (PM) pollutants at the wind speeds of 1.5 m/s and 0.5 m/s and reach a maximum adsorption efficiency of 99.5% for formaldehyde within 19 min, highlighting its potential for all-weather air purification via ROS-mediated environmental remediation.

Organic-inorganic hybrid perovskites are promising for optoelectronics owing to their high color purity, tunable bandgaps, and low nonradiative recombination rates. However, challenges such as rough surfaces and poor film-forming properties constrain the optoelectronic performance of light-emitting devices. Herein, the PEDOT:PSS film treated by oxygen plasma serves as the hole transport layer, while the formation of perovskite films is optimized by dual-additive doping of PEO and TPBi in ambient air. The results show that the PEDOT:PSS films with PSSH-rich after oxygen plasma treatment provide more nucleation sites, favoring the formation of the perovskite film. Meanwhile, the dual-additive prompts to form a dense and uniform film as well. The intrinsic mechanisms involve PEO as a binder to fill grain gaps and improve water-oxygen stability in the perovskite film, while TPBi acts as a passivator to stimulate uniform nucleation and dense crystallization, improving the grain coverage of the light-emitting layer. Under atmospheric conditions, all-solution processed perovskite devices reach a maximum luminance of 810.4 cd m −2 and a maximum current efficiency of 0.437 cd A −1 . This work highlights the significance of using oxygen plasma treatment and additives to improve the performance of perovskite films and achieve superior PeLEDs.

Solar photocatalytic degradation and adsorption using metalorganic frameworks (MOFs) offer safe and energy-efficient remediation for water contaminated with small organic pollutants, leveraging their semiconductor-like tunable band structures and inherent porosity. This study reports the de novo synthesis of a visible-light-responsive Ti@Ce MOF heterojunction composite for synergistic photocatalytic degradation and adsorption of recalcitrant organic contaminants. An in-situ growth strategy deposited NO.-functionalized UiO-66(Ce) onto NH 2 -modified MIL-125, forming an S-scheme heterojunction engineered for efficient visible-light-driven hydrogen peroxide (H 2 O 2 ) generation. This in-situ photogenerated H 2 O 2 acts as a potent oxidant, effectively degrading tetracycline. A significantly enhanced photocatalytic degradation rate constant ( k ) for tetracycline was observed, indicating boosted catalytic activity. Mechanistic analysis underscores the critical role of the S-scheme heterojunction in promoting charge carrier separation and enhancing H 2 O 2 production, thereby efficiently driving organic pollutant oxidative degradation. This work provides a novel strategic framework for designing multifunctional MOF composites, advancing high-performance, sustainable water purification technologies.

Luminescent solar concentrators (LSCs) are limited by intrinsic escape-cone losses that reduce their light-harvesting efficiency. In this work, we introduce a strip-array waveguide design that enhances light trapping to 85%, exceeding the theoretical limit imposed by total internal reflection (TIR). Using tetramethylammonium manganese chloride (TMAMnCl3) as the fluorophore, the device achieves an optical efficiency of 7.9% and a corresponding solar power conversion efficiency of 4.4% when all four edges are coated. The improved performance is attributed to reduced escape-cone loss, suppressed scattering, and a broad absorption spectrum (300–550 nm) that aligns with the high-intensity region of the solar spectrum. A stamping-assisted fabrication approach enables straightforward pattern definition and is compatible with various polymer matrices and emissive materials, offering a scalable route toward integrated LSC–PV devices.

In recent years, low-dimensional organic–inorganic hybrid metal halides have been widely studied in optoelectronics owing to their broadband emission and high quantum yields. However, there has been limited progress in blue-emitting material development. To address this challenge, we prepared two new zero-dimensional (0D) cadmium-based hybrid halides, [MeOP]CdBr4 (MeOP = 1-(2-methoxyphenyl)piperazine) and [FPhP]CdBr4 (FPhP = 1-(2-fluorophenyl)piperazine) with blue broadband emissions, originating from the radiative recombination of self-trapped excitons (STEs). Furthermore, a stable white light-emitting diode (LED) was fabricated using [MeOP]CdBr4 as blue phosphor, which achieved a high color rendering index (CRI) of 95.4. This study not only introduces two new blue light-emitting hybrid materials but also highlights their potential in solid-state lighting applications.

The attenuation coefficient of ultraviolet UV light is a critical factor influencing the mechanical properties of photocurable ceramics. Aiming to fabricate high-precision and high-performance ZrO2 ceramics, this study systematically investigates the impact of the UV attenuation coefficient on the polymerization kinetics of ZrO2 ceramic slurries. Through linear fitting, the absorption and scattering coefficients of the ZrO2 slurry were determined as 66 cm−1. By integrating the Beer-Lambert law, we further validated how the UV attenuation coefficient affects the variation in C=C double bond conversion within the cured slurry layers. Additionally, based on Mie scattering theory, although the incident energy was 52 mW cm−2 and slice thickness was 50 μm, the curing depth Cd and exposure energy In{E}_{o} is optimal. The ZrO2 ceramic was formed , in which the sintered sample density was 6.02 g cm−3 (99%).

Luminescent organic molecules play a pivotal role in the advancement of organic light-emitting diode (OLED) materials. Herein, a class of acenaphthylene-cored D–π–A-type molecules were designed and synthesized (isolated yields >85% for each step), wherein the acenaphthylene served as a conjugated bridge integrating a benzoxazole acceptor moiety and a triarylamine donor unit. Computational results showed a spatially segregated distribution of the frontier molecular orbitals, which achieved a small singlet–triplet energy gap (ΔEST = 0.1 eV). The corresponding OLED device emitted green light at 543 nm. Furthermore, this work represents the first combined application of acenaphthylene and benzoxazole in luminescent organic materials.

Artificial energy supply modules that can produce adenosine triphosphate (ATP) through natural or synthetic structures, are crucial for supporting artificial cells with therapeutic purposes. However, their advanced biomedical application is hindered by poor stability, short lifespan and low output efficiency. In this study, an artificial light-controlled energetic module with long-term activity, termed thylakoid-loaded microgel (TM), is created by encapsulating spinach-derived thylakoid into alginate/gelatin microgels. The TM effectively retains the photosynthetic light reactions of thylakoids, including the electron transfer capacity of photosystem II and ATP production, and releases the produced ATP to external environment. As a proof of concept, the TM successfully drives the luciferin/luciferase reaction both within and outside the microgel compartment. In addition, the encapsulated thylakoids exhibit a significantly prolonged activity, with the high photosystem II activity and ATP production lasting for at least 96 hours. The long-term activity is attributed to the oxidation shielding efficacy, protein and pigment degradation inhibition, and membrane structural stabilization. This study presents a strategy for developing artificial energy supply modules with efficient energy output and long-term activity, holding great promise in artificial cell construction and biosynthesis.

LED-based near-infrared (NIR) light sources are of considerable interest for advanced NIR spectroscopy technologies. However, LED "efficiency droop" presents a major challenge to achieving high-brightness NIR light. In this study, LaMgGa 11 O 19 :Cr 3+ (LMG:Cr 3+ ) ceramic was developed as a NIR color converter to achieve high-brightness laser-driven NIR light. The effects of fabrication temperature and Cr 3+ doping concentration on the luminescent properties of LMG:Cr 3+ ceramics were thoroughly investigated. Under blue light excitation, LMG:Cr 3+ ceramic exhibits a broadband NIR emission peak at 730 nm, with a high external quantum efficiency of 55.4 %. Due to its excellent heat dissipation performance and high-temperature stability, LMG:Cr 3+ ceramic can generate high-brightness NIR light, achieving an output power of 1.2 W when excited by a blue laser with power density of 7.50 W mm −2 . Finally, a laser-driven NIR light source has been successfully packaged, demonstrating the capability to meet various intelligent spectroscopy applications in biomedical imaging and non-destructive detection.

To mitigate solar heating in colored objects, fluorescent coloration has been proposed as an alternative to traditional absorptive pigments. However, the Stokes-shifted photons generated by fluorophores predominantly remain trapped by total internal reflection (TIR), increasing the parasitic solar absorption and the radiative thermal load. This work introduces a scattering-enhanced light extraction strategy that overcomes the TIR limit in fluorescent films. A sequential quadratic programming-driven optimization model establishes the theoretical minimum radiative thermal load for both traditional and fluorescent-colored surfaces. Results reveal that while traditional absorption-based color achieves only 19.3% sub-ambient cooling chromaticity in the CIE 1931 color space, light extraction technology expands the range from 26.7% to 64.9% for fluorescent color. TiO 2 nanoparticles enhance light extraction through multiple Mie-scattering, with Monte Carlo ray-tracing simulation identifying an optimal 0.5 wt% TiO 2 nanoparticle concentration yielding 85.9% light extraction efficiency, significantly outperforming the TiO 2 -free fluorescent film (25.3%) and a higher 15 wt.% concentration (66.6%). Outdoor experiments confirm the optimal 0.5 wt% sample exhibits a 4.1 °C temperature decrease compared to the control (0 wt.%) sample. This approach offers cost-effective scalability advantages over microtexture-based light extraction methods.

Miniaturized lasers with tailored lasing modes are critical for integrated photonics, demanding their high-level integration and 3D or multi-dimensional designability. Here, we demonstrate the intracavity light field modulation by integrating micro-optics into Fabry-Pérot (FP) microcavities using two-photon-lithography. Synergistic modulations of the internal element geometry and cavity configuration provide adjustable and stable resonance control. The quality factor of focusing micro-optics integrated microcavity is up to ∼ 5.8 × 10 5 from ∼ 10 3 in plane-parallel FP microcavities, while decreasing lasing thresholds to ∼ 0.3–2.5 µJ·mm −2 . The microlaser with an intracavity axicon generates stable Bessel-Gaussian beam with a ∼ 150 µm non-diffraction distance. A 2D Hermite-Gaussian mode selector with indices up to 19 is implemented by off-axis pumping. As a proof of concept, the biomimetic all-optical displacement perception inspired by biologically hair sensilla reaches a sensitivity of up to −1.13 nm·µm −1 . Its deep-learning-driven recognition based on lasing mode images is explored to obtain an accuracy over 88.94%. This work may promise small lasers with freely designed compact configurations and improved performance for diverse integrated applications.

The heteroatoms such as nitrogen, oxygen, and sulfur of organic inhibitor play a crucial role on its corrosion inhibition behavior. In order to reveal their adsorption behavior and inhibition performance under illumination condition on steel surface, this study selects L-cysteine as study object. On the basis of electrochemical measurement, surface analysis, and theoretical calculation, a promising increase in corrosion inhibition efficiency is observed when visible-light is impinged on steel surface in sodium chloride solution with L-cysteine. The enhanced performance is attributed to the sample surface photovoltaic effect, thereby facilitating both the thiol and the amino groups to tilt toward the surface.
