Claim 0:
1. A quantum dot material comprising a quantum dot body and a hole transport ligand bonded to the quantum dot body through a coordinate bond,
wherein the hole transport ligand comprises a carbazolyl group, at least one coordinating group and at least one crosslinking group having an unsaturated bond; both of the coordinating group and the crosslinking group are terminal groups of the hole transport ligand; and the coordinating group provides the coordinate bond,
wherein a total number of the coordinating groups and crosslinking groups of the hole transport ligand is not less than 3;
the hole transport ligand has a structural formula of:, wherein one or two of R1, R4 and R7 each have a terminal group of the coordinating group and other one or two of R1, R4 and R7 each have a terminal group of the crosslinking group, and R2, R3, R5, R6, R8 and R9 is H;
or R1, R3, R5, R6 and R8 each have the crosslinking group as a terminal group and R2, R4, R7 and R9 each have the coordinating group as a terminal group.
