Abstract: A quantum dot material includes: quantum dot bodies and a ligand material coordinated to the quantum dot bodies; the quantum dot material further includes: a cross-linking agent, the cross-linking agent includes at least two photoresponsive group and a linking group bonding the at least two photoresponsive groups. Under light illumination, each photoresponsive group in the at least two photoresponsive groups is bonded to the ligand material by a carbon-hydrogen insertion reaction to form a cross-linked ligand material; a solubility of the cross-linked ligand material in a solvent is less than a solubility of the ligand material and the cross-linking agent in the solvent.
