Abstract:
A method of preparing perovskite quantum dots is provided. The method includes: adding an organic ligand into a first precursor solution prepared by a first halide and a second halide to form a second precursor solution, or adding the organic ligand into a first poor solvent to form a second poor solvent; spraying the first precursor solution into the second poor solvent or spraying the second precursor solution into the first poor solvent by a spraying method to obtain a mixed solution including first perovskite quantum dots and second quantum dots; centrifuging the mixed solution to obtain supernatant and precipitate; and obtaining the first perovskite quantum dots and the second perovskite quantum dots from the supernatant and the precipitate, respectively. The first perovskite quantum dots are different from the second perovskite quantum dots.

Claim (Index 8):
The method of preparing the perovskite quantum dots of  claim 1 , wherein the first perovskite quantum dot has a sphere shape, and the second perovskite quantum dot has a cube or rectangular shape.
