Abstract: PURPOSE: A nanocomposite is provided to have complex spectrum contrary to existing quantum dots, and to have simple manufacturing process like existing quantum dots, thereby reducing manufacturing cost. CONSTITUTION: A nanocomposite comprises quantum dots combined from each other, and rare earth element complexes. The quantum dots are one or more selected from a group consisting of a family 12-16 compound, a family 13-15 compound, and a family 14-16 compound. The rare earth elements complexes comprise are earth materials combined each other, and ligand. The ligand is one or more selected from a group consisting of nitro, carbonato, nitrito, cyano, thiocyanato, isothiocyanato, hydroxo, aqua, ammine, carbonyl, and nitrosyl.

Abstract: PURPOSE: A synthesizing method of quantum dot of high efficiency is provided to prevent sudden degradation of luminous efficiency caused by ligand substitution method, and to convert ligand by only one solution injection, thereby providing simple and economic process. CONSTITUTION: A synthesizing method of quantum dot of high efficiency comprises: a step of synthesizing quantum dot under the presence of organic solvent of 100-350 °C; a step of adding X-Y-Z shaped ligand capable of being dispersed to organic solvent to the quantum dot; and a step of conducting reaction for 1-60 minutes at 100-350 °C. The quantum dot is one or more selected from a group consisting of a group 12-16 compound, a group 11-13-16 compound, a group 13-15 compound, and a group 14-16 compound.
