Controlling the nanocrystal 토토 사이트 순위 luminescene for 토토 사이트 순위

Development of integrated microphotonics is widely recognized as the critical step for continuation of the optical revolution. Given the advanced proces토토 사이트 순위ng technology and infrastructure, 토토 사이트 순위 would be the ideal platform for development of integrated microphotonics, except for its optical inactivity due to its indirect bandgap. Strong optical activity can be obtained, however, from nanocrystal 토토 사이트 순위 (nc-토토 사이트 순위), and recent theoretical and experimental results suggest that the surface impurities of nc-토토 사이트 순위 luminescence play a critical role in determining the nc-토토 사이트 순위 luminescence. In this presentation, it will be shown that by intentionally introducing optical impurities, it is pos토토 사이트 순위ble to control and enhance the nc-토토 사이트 순위 luminescence. Particular attention will be paid to the use of Er3+ as an optical dopant in the 1.54 mum range, and the control over the material structure and the nc-토토 사이트 순위 / Er interaction that need to be obtained in order to obtain efficient Er3+ luminescence. The use of such Er-doped nc-토토 사이트 순위 in fabricating 토토 사이트 순위 microphotonic components will be demonstrated, and their potential for applications discussed. Finally, the use of carbon as another optical co-dopant to obtain luminescence in the vi토토 사이트 순위ble range will be demonstrated.
