QUANTUM DOT LIGHT-EMITTING THIN FILM, PREPARATION THEREOF AND USE THEREOF IN WHITE-LIGHT MINI-LED DEVICE

WIPO Patent Application WO/2024/021759

A1

A quantum dot light-emitting thin film, the preparation thereof and the use thereof in a white-light Mini LED device. The quantum dot light-emitting thin film is made of a quantum dot light-emitting material. The quantum dot light-emitting material is prepared by embedding quantum dots into pore channels in the surfaces of mesoporous nanospheres, then wrapping the surfaces with transparent oxide shell layers, and finally embedding the spheres into an organic polymer; and the general chemical formula thereof is: M@N/P@Q, wherein M is quantum dots; @ represents embedding; N is mesoporous nanospheres; / represents core-shell; P is a transparent oxide shell layer; and Q is an organic polymer. The quantum dot light-emitting thin film has high light-emitting stability and brightness and low preparation cost.
