Summary: The study addresses the limited research on stretchable electroluminescent (EL) layers for LED devices and presents the concept of blending elastomers into conjugated polymers (CPs) to fabricate stretchable emission layers (EMLs) for stretchable polymer LEDs (PLEDs). The blended film exhibited good mechanical, electrical, and morphological properties, and the stretchable PLEDs maintained 50% of the maximum luminance upon 60% stretching.

Summary: In this paper, simulation models of gallium nitride nanostructure arrays were designed using COMSOL Multiphysics software based on finite element method. The study analyzed the effects of changes in the axial geometry of GaN nanowires on photoelectron concentration distributions performance and absorptivity. The results indicated that both truncated-corn and inverted-pencil arrays outperform nanorod arrays in boosting light absorption.

Summary: By using Ag nanowire top electrode, polarized LEDs based on 2D monolayer semiconductors (WSe2, MoSe2, and WS2) have been successfully achieved at room temperature with a degree of polarization (DoP) ranging from 50% to 63%. The highly anisotropic electroluminescence (EL) emission originates from the 2D/Ag interface via the electron/hole injection and recombination process, and the EL emission is further enhanced by the polarization-dependent plasmonic resonance of the Ag nanowire. These findings provide new insights for designing polarized 2D LED devices at room temperature and may promote the development of miniaturized 2D optoelectronic devices.

Summary: In this study, CuS@ZnIn2S4 p-n heterojunction was prepared for the first time using the ultrasonic composite method. Under LED visible light excitation, the CuS@ZnIn2S4-3 nanocomposite achieved a methylene blue (MB) degradation efficiency of 95.8% in 60 minutes. Compared to ZnIn2S4, CuS@ZnIn2S4-3 exhibited a widened spectral response range and approximately 6 times increased optical absorption capacity. Electrochemical results demonstrated that CuS@ZnIn2S4-3 had excellent photogenerated carrier separation efficiency, with a 2.2 times increased photocurrent and a 4.16 times reduced impedance compared to ZnIn2S4. Finally, the photocatalytic mechanism of CuS@ZnIn2S4 was extensively explored.

Summary: This study aims to enhance the photocatalytic performance of K2Ti4O9 by intercalating Fe3+ cations, allowing it to respond to visible light. The degradation of MB by K2Ti4O9 treated with different concentrations of Fe3+ cations was studied to determine the optimal treatment concentration and evaluate the photocatalytic performance. The structure, morphology and energy band characteristics of the photocatalyst were confirmed using XRD, SEM, XPS, UV-vis, PL, and an electrochemical workstation.

Summary: Bi0/BiVO4 was synthesized using ascorbic acid, and its microstructure, morphology, optical properties and photogenerated carriers separation behavior were investigated. The photocatalytic degradation of RhB by Bi0/BiVO4 under visible light irradiation was studied, showing that the photocatalytic performance of Bi0/BiVO4 is significantly improved compared to BiVO4. This enhancement is mainly attributed to the surface plasmon resonance effect of Bi0 deposited on the surface of BiVO4, which expands the light response range and accelerates the separation of photogenerated carriers. This study provides valuable insights for the preparation of excellent catalysts.
