Claim 4:
5. A method for producing a quantum dot, the method comprising:
synthesizing a quantum dot represented by AgInE2 (E is at least one of tellurium, selenium, and sulfur) from a silver raw material, an indium raw material, and a chalcogenide raw material (chalcogenide is at least one of tellurium, selenium, and sulfur) by:
sequentially dissolving one or two of the silver raw material, the indium raw material, the chalcogenide raw material, and a ligand in a high-boiling point solvent heated from 60° C. to 120° C., the high-boiling point solvent having a boiling point of at least 150° C.;
sequentially adding the other remaining materials of the silver raw material, the indium raw material, the chalcogenide raw material, and the ligand; and
synthesizing the quantum dot by raising a temperature of the resultant solution to a reaction temperature of 180° C. or higher and 250° C. or lower after adding all of the raw materials and the ligand.
