Synthesis, Structures, and Optical Properties of Semiconductor Perovskite Nanoparticles CsBX3 (B = Pb, Mn; X = Br, Cl)
摘要
Abstract—
Currently, ABX3 nanoparticles (NPs) based on lead halides attract the attention due to their unique optical properties and a wide range of applications. The preparation of NPs with lead as a partial or complete replacement is particularly interesting because of the toxicity of this chemical element and most of its compounds. In this study, we propose a modified method for perovskite NPs synthesis using manganese as a partial replacement for lead. The results obtained describe the structures, shapes, and dimensions of the synthesized nanoparticles. It has been shown that partial replacement of lead with manganese leads to the appearance of new photoluminescence bands in the region of 600 nm.
