Systematic Microwave-Assisted Postsynthesis of Mn-Doped Cesium Lead Halide Perovskites with Improved Color-Tunable Luminescence and Stability.

ABSTRACT: The metal doping at the Pb²⁺ position provides improved luminescence performance for the cesium lead halide perovskites, and their fabrication methods assisted by microwave have attracted considerable attention due to the advantages of fast heating and low energy consumption. However, the postsynthetic doping strategy of the metal-doped perovskites driven by microwave heating still lacks systematic research. In this study, the assembly of CsPbBr₃/CsPb₂Br₅ with a strong fluorescence peak at 523 nm is used as the CsPbBr₃ precursor, and through the optimization of the postsynthetic conditions such as reaction temperatures, Mn²⁺/Pb²⁺ feeding ratios, and Mn²⁺ sources, the optimum Mn²⁺-doped produc
