CsPbX3 inorganic perovskites have gained widespread attention due to the excellent stability and interesting properties. This article focuses on the exciton properties of CsPbBr3 with different layer numbers. The electronic and optical properties are also investigated. The distribution of excitons (electrons and holes) is closely related to the density of states near the bottom of the conduction band...
The synthesis of REFe0.5Cr0.5O3 (RE = La, Y) using the sol–gel method is focused and their structural differences are investigated. The results of X‐ray diffraction show that the change of ion radius at position A leads to varying degrees of octahedral distortion and spatial group structure. The scanning electron microscopy analysis reveals micron‐level particles with clear boundaries, while energy‐dispersive...
