Abstract
According to the preparation method of the quantum dots substrate, a first ligand modifies on an outer surface of each of the quantum dots, a second ligand modifies on an outer surface of each of nanoparticles. And one of the first ligand and the second ligand is provided as a compound containing a sulfhydryl group and the other as a compound containing a double bond, so that after the quantum dots and the nanoparticles are co-deposited on a first electrode or on a second electrode, the first ligands and the second ligands can be subjected to a thiolene group click reaction so as to be crosslinked under the initiation of photoinitiators, thereby enabling the quantum dots and the nanoparticles to be connected. An obtained pattern of the patterned quantum dots thin film is consistent with a pattern of the first electrode or of the second electrode.
