Patent ID: 11332661

Abstract:
A modified perovskite quantum dot material, a fabricating method thereof, and a display device are provided. Hydroxyl-modified perovskite quantum dots are obtained by adding an excess amount of hydroxyl-containing surface ligands to a solution of synthesized perovskite quantum dots. After high-speed centrifugation, the obtained perovskite quantum dots are redispersed into a non-polar alkyl solvent to form a solution. Further, an excess amount of ethyl orthosilicate is added to the solution, and after exposing the solution for a long period of time, the ethyl orthosilicate is hydrolyzed to form a triethoxysilane group. After centrifugation, modified perovskite quantum dots wrapped by the triethoxysilane groups are obtained, which effectively improves stability of the perovskite quantum dots.
