| Outline of Final Research Achievements |
This project suggested to synthesize luminescence silicon (Si) quantum dots (QDs) and to develop Si QD LED. To accomplish this project, we synthesized the Si QDs by utilizing three different methods; pulsed laser ablation, chemical synthesis, and thermal pyrolysis. The SiQDs, had different surface functional groups, were synthesized by the methods and showed blue, blue-green, orange, and red luminescence. As for QD LEDs, we developed Si QD LED using colloidal solutions of Si QDs via solution processes. In particular, a blue-white LED of Si QDs working as a light emitter attached much attention in academia and media for domestic and world wide.
