Abstract
Disclosed are a core-shell quantum dot, a quantum dot light-emitting device, a display apparatus and a manufacturing method. The core-shell quantum dot includes: a core part; a shell layer arranged on at least part of a surface of the core part, and including metal ions; and a chelating ligand connected with the metal ions, where the chelating ligand and the metal ions form a closed ring structure connected with the shell layer.
Claims20
A core-shell quantum dot, comprising:
- a core part;
- a shell layer, arranged on at least part of a surface of the core part, and comprising metal ions;
- and
- a chelating ligand, connected with the metal ions;
- wherein the chelating ligand and the metal ions form a closed ring structure connected with the shell layer.
2 more elements
A manufacturing method for a core-shell quantum dot, comprising:
- adding quantum dots connected with a first ligand, and a metal ion-containing compound into a first solvent;
- carrying out a first reaction to replace the first ligand with the metal ions to obtain quantum dots with a shell layer comprising the metal ions;
- dissolving the quantum dots in a second solvent, and adding a chelating ligand into the second solvent;
- and
- carrying out a second reaction to connect the chelating ligand with the metal ions to obtain quantum dots connected with the chelating ligand through the metal ions.
