摘要： There are provided green-emitting quantum dots (QDs) including I-III-VI type ternary Cu—Ga—S core QDs and ZnS multishell wherein Cu:Ga is 1:10 to 1:1, and a fabricating method thereof. Integration of these QDs and red-emitting QDs into a blue LED leads to the fabrication of a white light-emitting device with high color rendering index. There are also provided blue-emitting QDs including I-III-VI type quaternary Zn—Cu—Ga—S or Cu—Ga—Al—S core QDs and ZnS multishell, and a fabricating method thereof. An electrically-driven blue light-emitting device with a QD emitting layer including these QDs interposed between a hole transport layer and an electron transport layer is fabricated.
