Abstract
The invention provides a preparation method of ZnCdA quantum dot capable of emitting white light, in which A is S or SSe; 0<x<1 and 0<y<1. The method includes preparing a sulfur-containing organic solution; mixing a zinc-containing precursor and a cadmium-containing precursor with an organic acid, and dissolving them in a co-solvent to obtain a homogeneous solution; and mixing sulfur-containing organic solution with the homogeneous solution to produce ZnCdA quantum dot.
