Bright CsPbBr Perovskite Nanocrystals with Improved Stability by In-Situ Zn-Doping.

In this study, facile synthesis, characterization, and stability tests of highly luminescent Zn-doped CsPbBr perovskite nanocrystals (NCs) were demonstrated. The doping procedure was performed via partial replacement of PbBr with ZnBr in the precursor solution. Via Zn-doping, the photoluminescence quantum yield (PLQY) of the NCs was increased from 41.
