Summary: Sb3+-doped halide perovskites have potential for solid-state lighting due to their diverse colors and high efficiency. However, there is a critical issue of mismatched excitation energy with commercial UV chips. In this study, a Bi3+ codoping strategy was used to modulate the excitation spectrum in inorganic perovskites. The interaction between Bi3+ and Sb3+ persists even at low doping concentrations, resulting in enhanced splitting of the A band and redshift of the low-energy branch.

Summary: Submicron-sized quasi-spherical zinc oxide (ZnO) particles were prepared by wet ultrafine grinding under different conditions. The effects of solution type, acid or alkali concentration, solid content, and grinding time on the particle size, distribution, and sphericity of ZnO particles were investigated. The results showed that submicron-sized quasi-spherical particles could be obtained by grinding micron-sized ZnO particles in an acetic acid solution with specific conditions, leading to chemical dissolution, narrower size distribution, and enhanced sphericity. Furthermore, the grinding mechanism of ZnO particles was analyzed using selection and breakage functions.

Summary: Compared to polymer-based organic solar cells, all-small-molecule organic solar cells (ASM-OSCs) have gained attention due to their well-defined chemical structures, lower batch-to-batch variation, straightforward synthesis and purification procedures, and easy to modulate properties. Recent developments in small molecule donors have enabled ASM-OSCs to achieve power conversion efficiencies in excess of 17%, gradually approaching those of polymer-based devices, and demonstrating considerable potential for commercialization. However, structural and morphological features in the all-small-molecule blend films play a crucial role in the photoelectric performance.

Summary: Ionic liquids (ILs) have wide applications in controlling the crystallization process and enhancing the performance of perovskite devices. However, there is limited research on the effects of ILs on perovskite devices prepared using the two-step method. This study investigates the effects of a specific IL as an additive in the perovskite precursor solution on the morphology, defect density, and photovoltaic performance of perovskite thin films. The results show that the IL has a strong chemical affinity with perovskite components, leading to inhibition of ion migration and optimization of perovskite morphology.

Summary: Designing crystalline porous materials with efficient hydrogen evolution is a promising strategy. Covalent organic frameworks (COFs), especially sp(2)c-COFs, have good stability and are regarded as outstanding photocatalysts. By designing and synthesizing benzothiadiazole and its derivative-based isoreticular sp(2)c-COFs, we achieve higher photocatalytic activity with broader light-harvesting ranges. The average hydrogen evolution rates of HIAM-0001 and HIAM-0004 are 1410 μmol g(-1) h(-1) and 1526 μmol g(-1) h(-1) under visible-light illumination (λ > 420 nm), respectively. This work provides a new guidance for the rational design of efficient photocatalysts for hydrogen generation.
