Brightly Luminescent and Colour‐tunable CsPbBr3 Nanocrystals with Enhanced Stability and Room Temperature Cubic Structure Through Codoping with MnCl2

Abstract

Lead halide perovskites have attracted much attention from the scientific community in recent years due to their attractive properties and their proven potential in many applications. Nevertheless, their stability and lead toxicity have remained a problem. Herein, we are investigating the potential of manganese as a divalent dopant to offer better stability and replace a fraction of the toxic lead ions. Moreover, we used the reverse microemulsion method to obtain tunability in emission and band gap by doping cesium lead bromide. Furthermore, we managed to obtain cubic cesium lead bromide particles at room temperature as a result of doping.This article is protected by copyright. All rights reserved.
