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.

Method of forming gigantic quantum dots

Provided are Gigantic quantum dots and a method of forming gigantic quantum dots. Each of the gigantic quantum dots includes a core constituted of CdSe, a shell constituted of ZnS, and an alloy configured between the core and the shell. The core is wrapped by the shell. The alloy constituted of Cd, Se, Zn and S, wherein a content of the Cd and Se gradually decreases from the core to the shell and a content of the Zn and S gradually increases from the core to the shell. A particle size of each of the gigantic quantum dots is equal to or more than 10 nm.
