Abstract
Disclosed in the present application are quantum dot ink, a quantum dot layer, and a quantum dot photoelectric device. The quantum dot ink comprises a solvent and a quantum dot material. The quantum dot material comprises a quantum dot body and a ligand coordinated with the surface of the quantum dot body. The ligand comprises a first ligand and a second ligand, the second ligand and the solvent both comprise at least one ester group, and the ratio of the ligand to the quantum dot material is greater than 0.15.
