Summary: The toxicity of lead-based halide perovskites limits their wide application in optoelectronics. The lead-free perovskite Cs2AgBiBr6 is a promising candidate due to its long carrier lifetime and outstanding stability. However, its large bandgap hinders absorption in the visible region, limiting its photoelectric properties. By facile elemental doping or substitution, Cs2AgBiBr6 can potentially be used in both visible and near-infrared regions. Band-edge adjustment or deep-energy-level doping can expand its absorption range, making it suitable for solar cells and photodetector applications.

Summary: This study proposes a strategy to achieve efficient near-infrared emission in Cs2AgInCl6 microcrystals by codoping with Sb3+ ions. The introduction of Sb3+ ions creates a new optical absorption channel at longer wavelengths and reduces the electron bandgap. The co-doped Cs2AgInCl6 shows efficient NIR emission under excitation, attributed to effective energy transfer from Sb3+ to Ln3+ (Ln=Nd, Yb) ions.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.
