Document Type and Number:
WIPO Patent Application WO/2022/227661
Kind Code:
A1
Abstract:
The present application discloses a quantum dot film and a preparation method therefor, and a preparation method for a quantum dot light-emitting diode. The preparation method for a quantum dot film comprises the following steps: providing an initial quantum dot film; and processing the initial quantum dot film by using a proton reagent to obtain a quantum dot film. According to the preparation method for a quantum dot film, surface defects of quantum dots can be passivated, the quenching of excitons due to defect states is reduced, and finally the luminous efficiency and the service life of the quantum dot film are improved.
