White-light-emitting diodes using GaN-excited CdSe/CdS/ZnS quantum dots

- WLEDs were fabricated using blue GaN chips and green- and red-emitting CdSe/CdS/ZnS quantum dots.
- Warm and cold white emissions were confirmed with color temperature from 4000 to 9000 K.
- Variation of color coordinates and color temperature were investigated and analyzed at deferent bias.
- Stability of white emission was analyzed with the increase of working time.
