Abstract
A quantum dot may include a core including copper (Cu), a Group III element, and a Group VI element, and a shell covering the core and including zinc (Zn) and a Group VI element, wherein an atomic ratio of Zn/Cu is in a range of about 1 to about 4.
Claims20
A quantum dot comprising:
- a core comprising copper (Cu), a Group III element, and a Group VI element;
- and
- a shell covering the core, the shell comprising zinc (Zn) and a Group VI element,
- wherein an atomic ratio of Zn/Cu is from about 1 to about 4.
