Tuning the optical properties of MAPbBr3 perovskite nanocrystals via alkali metal ions doping
the doping of Cs and Rb cations into MAPbBr 3 PeNCs to optimize their morphology, crystal structure, and optical properties. It is found that rubidium cations doping can greatly enhance the photoluminescence intensity of the MAPBBr 3 PeNCs, whereas cesium cations can improve the structural stability owing to the increased valance bond intensity. This work provides useful thoughts for the synthesis of high-performance optoelectronic devices based on mixed-cation PeNCs.
