  • Perovskite quantum dot material
    Patent number: 10731075
    Abstract: Provided is a hybridized perovskite quantum dot material. The quantum dot material includes a kernel and surface ligands. The kernel is formed by R1NH3AB3 or (R2NH3)2AB4, where R1 is methyl group, R2 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 R1NH3 or R2NH3 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.
    Type: Grant
