QUANTUM DOT AND PREPARATION METHOD THEREOF, AND LIGHT-EMITTING DEVICE

Abstract: the present disclosure provides a quantum dot and preparation method thereof, and light-emitting device. the method of preparing the quantum dot comprising: providing a single molecule source precursor solution, the single molecule source precursor solution comprises a single molecule source precursor compound comprising a first metal ion and a first anion; heating the single molecule source precursor solution to obtain a sulfur-containing quantum core; and forming one or more shell layers on the surface of the sulfur-containing quantum dot core to obtain the quantum dot. the sulfur-containing quantum dot core prepared by the method have few defects, thereby the defects of the generated quantum dot are reduced.
