Abstract

The present disclosure provides a quantum dot (100) having has a core-shell structure and exhibiting superior quantum efficiency and optical stability. The quantum dot may be composed of a five element system of Zn-Cu-ln-P-S. The quantum dot may include: a core (30) formed of ln(Zn)P material and doped with copper (20); a first shell (40) formed of Cu-Zn-ln-S material and surrounding the core; and a second shell (50) formed ZnS material and surrounding the first shell.
