The electrical and optical properties of Janus M2S2ClF and its stress modulation function have been systematically studied by first principles method. The stability of the structure was verified by AIMD. The bandgaps of Janus Al2S2ClF, Ga2S2ClF and In2S2ClF under PBE functional are 2.02, 1.03 and 1.22 eV, respectively. The optical parameters show that the Janus Al2S2ClF exhibits high optical absorption coefficient, low reflectance, and low loss function, which has great potential for application in ultraviolet detection and other optoelectronic devices compared with Janus Ga2S2ClF and In2S2ClF. In the strain range of -4% to 4%, it is found that the light absorption coefficient of Janus Al2S2ClF is significantly changed by strain, and the absorption coefficient under -4% stress is 8.9 times that under 4% stress. Meanwhile, the bandgaps of Janus Ga2S2ClF is significantly changed by stress, which can achieve regulation from 0.47 to 2.57eV. Conclusion that the stress has a significant regulatory effect on its electronic and optical properties, which provides a theoretical basis for realizing high performance and controllable optoelectronic devices. © 2025 SPIE.

Solar photovoltaic modules have a single color that cannot meet the requirements of architectural aesthetics. In this paper, starting from the glass cover of thin-film solar cells, to the color-coated glass (coral, green and blue) is prepared by magnetron sputtering with the aid of TFCalc software. TiO2/SiO2/TiO2/SiO2 multilayers with different thickness were prepared with an average transmittance above 73 %. The angle stability of the film color was investigated, and the color stability under different viewing angles can be improved by using high haze frosted glass as the substrate for the preparation of colored films. An average visible transmittance of 75.5 % was obtained in the coral film with the covering of the frosted glass. The use of high haze frosted glass to prepare colored film not only improves the transmittance of coated glass, but also reduces the angle dependence of color film, reduces light pollution, and facilitates the development of industrialization and PV building integration. © 2025 Elsevier Ltd and Techna Group S.r.l.

glass enamel coatings are widely used to protect metal against corrosion and weathering due to their exceptional chemical stability. However, the application potential of enamel coatings will be further enhanced if their mechanical properties, particularly impact resistance and toughness, can be improved. In this study, we investigated the influence of varying amounts of alumina fibers on the microstructure, phase composition, and mechanical properties of enamel coatings by fabricating composite enamel coatings. The impact strength, hardness and modulus of the resulting materials were evaluated by falling ball impact tests and nanoindentation tests. The results showed that the alumina fibers were well bonded to the enamel matrix, and the coating surface roughness and contact angle increased with fiber addition. The coating had the lowest porosity and best impact resistance at 0.5 wt% fiber addition. At this point, the modulus and hardness of the composite enamel coating demonstrated improved stability, with the overall hardness reaching its maximum value, and excessive addition of alumina fibers can lead to a reduction in coating performance. As a result, the alumina fibers appear feasible to use as reinforcing material to produce high performance composite enamel coatings. © 2025 Elsevier Ltd and Techna Group S.r.l.

Fabrication of Ultra-Low Absorption Thin Films via Ion Beam Assisted Electron Beam Evaporation

引用

High Power Laser Science and Engineering 2025年

High-power laser systems require thin films with extremely low absorption. Ultra-low absorption films are often fabricated via ion beam sputtering, which is costly and slow. This study analyzes the impact of doping titanium and annealing on the absorption characteristics of thin films, focusing on composition and structure. The results indicate that the primary factor influencing absorption is composition. By suppressing the presence of electrons or holes that do not form stable chemical bonds can significantly reduce absorption;For amorphous thin films, the structural influence on absorption is relatively minor. Thus, composition control is crucial for fabricating ultra-low absorption films, while the deposition method is secondary. Ion beam assisted electron beam evaporation, which is relatively seldom used for fabricating lowabsorption films, was employed to produce high-reflectivity films. After annealing, the absorption at 1064 nm reached 1.70 ppm. This method offers a cost-effective and rapid approach for fabricating ultra-low absorption films. © The Author(s), 2025.

Structure, mechanical properties, and diffusion kinetics of chemical strengthening ultra-thin aluminosilicate glass by two-step method

引用

Ceramics International 2025年

Chemically strengthening high aluminosilicate glass constitutes a vital component in electronic display devices, and two-step strengthening can further enhance the mechanical properties and stability of conventional chemically strengthening glass. The influence of temperature and time factors on the structure, mechanical properties, and diffusion kinetics of the ultra-thin aluminosilicate glass during the two-step chemical strengthening process was investigated through differential scanning calorimeter (DSC), X-ray fluorescence spectrometer (XRF), Raman spectroscopy, electron probe micro-analyzer (EPMA), and other performance tests. The results demonstrate that as depth increases, the glass structure transitions from loose to more compact, and the extension of the exchange time in the second step will lead to the occurrence of structural relaxation in the glass. The calculation results of diffusion coefficients and activation energy indicate that the diffusion coefficient exhibits three distinct stages as depth increases, the activation energy first decreases and then increases with increasing depth. This may be related to changes in glass structure and concentration gradients. As the temperature for the second step of chemical strengthening increases, both compressive stress (CS) and depth of layer (DOL) exhibit a trend of first increasing and then decreasing. An extension in time leads to a decline in CS but an increase in DOL, which is a consequence of the combined effects of diffusion and stress relaxation. The trends in Vickers hardness and four-point bending strength are identical to that of CS. Although the CS achieved through the two-step method is slightly lower than that obtained by the one-step method, the two-step strengthening glass exhibits superior mechanical properties due to the inward shift of the potassium ion peak and a higher DOL. © 2025 Elsevier Ltd and Techna Group S.r.l.

A series of Ce3+-doped Gd2O3-GdF3-Al2O3-B2O3-SiO2 glass scintillators (GSCx and GLCx) were successfully synthesized in reducing atmosphere for future imaging application. The transmittance of GSCx glasses exceeds 85 % in range of 500–800 nm, and the cut-off edge red shifts as the Ce3+ concentration increases. In photoluminescence (PL), GSCx glass scintillators have a 360–600 nm broadband emission with a shoulder peak at around 450 nm. Meanwhile, the PL lifetime of GSCx glasses is close to the CeF3 crystals, and the PL QY of GSC3 glass scintillator reaches up 70.2 %. For scintillation application, the integral XEL intensity of GSC2 and GSC3 glasses is 31.3 % and 24.4 % of that of BGO crystal. GLC2 and GLC3 glasses exhibit similar spatial resolution of approximately 7 lp·mm−1. Moreover, the light yields of GSC2 and GSC3 glass scintillator are 1702 and 1690 ph/MeV excited by γ-ray, respectively. The nonproportionality of GSCx glasses is less than 3 % in the range of 100–1400 keV due to the large density and Zeff. As Ce3+ concentration increases, both the fast and slow components of the glasses decrease (103.7 ns–89.7 ns, 1454.4 ns–1012.8 ns), and the proportion of fast component also increased from 3.3 % to 4.7 %. For γ-ray imaging, the scintillation light events of the glass can be observed from SiPM array, and the central position (−2, −1) have the highest count rate of the system. The results show that GSCx and GLCx glass scintillators deserve further development for future applications. © 2025

Herein, a novel preparation of nitrogen-doped carbon (Co/NC) with Co nanoparticles capped onto graphitic carbon nitride (g-C₃N₄) nanocomposite was developed for detecting the synthetic carcinogenic antioxidant tert-butylhydroquinone (TBHQ). The novel electrochemical sensor equipped with g-C₃N₄/Co/NC derived by solid pyrolysis of g-C₃N₄/ZIF-67. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and electrochemical characterizations showed that g-C₃N₄/Co/NC had the advantages of high electrochemical active area, stable porous framework structure and excellent conductivity. The as-prepared g-C₃N₄/Co/NC sensor exhibited excellent properties towards TBHQ in a wide linear range (0.05–10 μM and 10–100 μM) with a low limit of detection (LOD = 14 nM, S/N = 3) as well as good sensitivity (5.538 μA·μM⁻¹·cm⁻² and 1.043 μA·μM⁻¹·cm⁻²). Moreover, it was found that the g-C₃N₄/Co/NC based sensor expressed superior selectivity, reusability and reproducibility. Also, for real sample analysis, food samples like rusk and potato chips were investigated, yielding satisfactory recoveries. © 2025

Inorganic CsPbI3 perovskite solar cells (PSCs), with outstanding thermal stability and appropriate optical band gap, are regarded as promising candidates for efficient single solar cells and the top sub-cell in tandem solar cells. Nevertheless, the substantial internal defect recombination and stringent preparation process conditions impede its further advancement. To obtain stable β-CsPbI3 film under open-air conditions, 1,4-phenyldimethylamine iodine (PhDMAI2) is selected as additive for the first time to prevent water erosion and regulate the intermediate phase transition during annealing. The systematic experimental results reveal that PhDMAI2 can accelerate the rate of intermediate phase conversion to β-CsPbI3 and build better energy level structure between perovskites (PVK) and hole transport layer (HTL), which effectively diminishes the quantity of pinholes and enhances the transportation and extraction of charge carriers at the interface. To further expand the application field in tandem or flexible devices, RbCl-doped SnO2 is adopted to replace the commonly used high temperature TiO2 as the electron transport layer (ETL), which not only enhances the electron transport capacity but also reduces the manufacturing temperature to below 200 ℃. Finally, the CsPbI3 PSCs with a PCE of 18.54% was achieved via a doping solvent engineering, which is one of the highest PCE values of SnO2 based CsPbI3 PSCs fabricated in ambient air. © 2025, The Authors.
