| titleOfInvention | Core-shell type quantum dots and method of forming the same |
| abstract | Provided is a core-shell type light-emitting quantum dot, including an alloy type core consisting of Cd, Se, Zn, and S, and a shell layer having a zinc blende structure and being coated on the surface of the alloy core, wherein the element ratio of each of Zn and S accounts for 30 to 50% of the overall core, and the content of Cd and Se gradually decreases outward from the core center. Also provided is a method for preparing the core-shell type light-emitting quantum dot. By having the alloy core and the shell layer with a zinc blende structure, the core-shell type quantum dot can achieve quantum efficiency of 95%, and have high temperature resistance and excellent water- and oxygen-barrier performance. |
