Abstract
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.
