CsPbBr3 perovskite quantum dots (PeQDs) show excellent luminescence properties with a narrow FWHM but are easily destroyed by heat and polar solvents. In this study, CsPbBr3 QDs coated with a protective layer of PbBr2 were fabricated. In addition, the electrostatic spraying deposition (ESD) method, which is capable of forming uniform thin films at a low cost, was used to prepare PeQDs thin films, and their photoluminescence (PL) properties were evaluated.
