Title:
QUANTUM DOT FILM, AND QUANTUM DOT LIGHT-EMITTING DIODE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/082967
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a quantum dot film, and a quantum dot light-emitting diode and a preparation method therefor. The quantum dot film comprises a first quantum dot, a second quantum dot and a first ligand. By means of the first ligand, a first exciton generated by the first quantum dot can be stacked with a second exciton generated by the second quantum dot, and the quantum dots of the whole hybrid system have the advantages of quantum dots of two different types by means of the stacking effect between the excitons, such that the light emission performance of the quantum dot light-emitting diode is improved.
