  • Core-shell quantum dot, preparation method thereof, and electroluminescent light-emitting device containing the same
    Patent number: 11912919
    Abstract: This present disclosure provides a core-shell quantum dot, a preparation method thereof, and a light-emitting device containing the same. The core of the core-shell quantum dot is CdSeXS(1-X), and the quantum dot shells include a first shell and a second shell, the first shell being selected from one or more of ZnSe, ZnSeYS(1-Y) and Cd(Z)Zn(1-Z)S, the second shell covering the first shell being one of Cd(Z)Zn(1-Z)S and ZnS, the maximum emission peak of the core-shell quantum dot is less than or equal to 480 nm, 0<X<1, 0<Y<1, 0<Z<1. The CdSeXS(1-X) core has a smaller bandgap and a shallower HOMO energy level, making hole injection easier.
