Abstract
Provided is a method of forming gigantic quantum dots including following steps. A first precursor by mixing zinc acetate (Zn(ac)), cadmium oxide (CdO), a surfactant, and a solvent together and then performing a first heat treatment is provided. The first precursor includes Zn-complex having the surfactant and Cd-complex having the surfactant. A second precursor containing elements S and Se and trioctylphosphine (TOP) is added into the first precursor to form a reaction mixture. A second heat treatment is performed on the reaction mixture and then cooling the reaction mixture to form the gigantic quantum dots in the reaction mixture.
