Abstract
Provided is a hybridized perovskite quantum dot material. The quantum dot material includes a kernel and surface ligands. The kernel is formed by RNHABor (RNH)AB, where Ris methyl group, Ris an organic molecular group, A is at least one selected from Ge, Sn, Pb, Sb, Bi, Cu and Mn, B is at least one selected from Cl, Br and I, A and B form a coordination octahedral structure, and RNHor RNHis filled in gaps of the coordination octahedral structure. The surface ligand is an organic acid or organic amine. The quantum dot material has a high fluorescence quantum yield.
