| description | The invention discloses a method for stabilizing all-inorganic perovskite quantum dots CsPbX3, wherein X is a Cl, Br, I, Cl/Br and Br/I mixed halide system. The method comprises the following steps: taking polydimethylsiloxane as a substrate; during preparation, preparing inorganic perovskite quantum dots containing different holagen elements by a thermal injection method, dispersing the inorganicperovskite quantum dots into normal hexane or methylbenzene and storing for retention; mixing polydimethylsiloxane and a curing agent uniformly, pouring the mixture into a solvent containing the quantum dots to form mixed liquid, putting the mixed liquid into a vacuum drying box and drying only for 6 to 8 hours to prepare a composite membrane, so that the time is greatly shortened and the time cost is reduced; meanwhile, the method is simple to operate, has good market value and is easy to popularize. After 100 days, the fluorescence property of the composite membrane is basically unchanged,so that after the perovski |
