Influence of Ferrous Metal Chloride on Photoluminescence Properties of Fully-Inorganic Lead Halide Perovskite Nanocrystals
CsPbCl3 nanocrystals (NCs) are prepared by the supersaturated recrystallization process at room temperature using ferrous metal chlorides as the chlorine sources. The Cl - ions react with Cs + and Pb 2+ to form CsPbCl3 NCs. The photoluminescence of the as-obtained NCs is not completely quenched by adding Fe 3+, Fe 2+, Co 2+, and Ni 2+. However, the as-synthesized NCs emit pure blue photoluminescence excited by 365 nm ultraviolet light. Especially, the quantum efficiency is slightly higher than that of NCs using lead chloride as the chlorine source.
