Document Type and Number:
WIPO Patent Application WO/2023/108456
Kind Code:
A1
Abstract:
A light-emitting device and a manufacturing method therefor, and a light-emitting apparatus, which relate to the technical field of semiconductors. The light-emitting device comprises a substrate, and an auxiliary layer and a quantum dot layer, which are arranged on one side of the substrate in a stacked manner, wherein the auxiliary layer is arranged close to the substrate, and the material of the auxiliary layer comprises a non-polar polymer; and the quantum dot layer comprises quantum dots and a first ligand material which is coordinated with the quantum dots, and the properties of the first ligand material change under the action of illumination, such that the solubility of the quantum dot layer in an organic solvent is changed.
