In order to optimize the influence of reaction process on the quality of synthesized perovskite quantum dots(QDs) and the QDs thin films
cesium acetate is used as the raw material for the synthesis of precursors because of its better solubility than cesium carbonate. A series of properties of quantum dots and films prepared under different conditions were characterized. CsPbBr
