Abstract
A quantum dot having core-shell structure, including a core formed of ZnOSof wurtzite crystal structure of hexagonal crystal system; a first shell covering the core, and formed of AlGaInN of wurtzite crystal structure of hexagonal crystal system; and a second shell covering the first shell, and formed of ZnOSof wurtzite crystal structure of hexagonal crystal system. At least one of v, x, y, and z is not zero and is not one; differences between the lattice constants along a-axis of the core, the first shell and the second shell are not greater than 1%; and the core, the first shell and the second shell form band offset structure of type II.
