摘要: Provided is a hybridized perovskite quantum dot material. The quantum dot material comprises a kernel and surface ligands. The kernel is formed by R 1 NH 3 AB 3 or (R 2 NH 3 ) 2 AB 4 , where R 1 is methyl group, R 2 is 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 R 1 NH 3 or R 2 NH 3 is 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.
