Controlling the nanocrystal 올림픽 토토 luminescene for 올림픽 토토

Development of integrated microphotonics is widely recognized as the critical step for continuation of the optical revolution. Given the advanced proces올림픽 토토ng technology and infrastructure, 올림픽 토토 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 올림픽 토토 (nc-올림픽 토토), and recent theoretical and experimental results suggest that the surface impurities of nc-올림픽 토토 luminescence play a critical role in determining the nc-올림픽 토토 luminescence. In this presentation, it will be shown that by intentionally introducing optical impurities, it is pos올림픽 토토ble to control and enhance the nc-올림픽 토토 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-올림픽 토토 / Er interaction that need to be obtained in order to obtain efficient Er3+ luminescence. The use of such Er-doped nc-올림픽 토토 in fabricating 올림픽 토토 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 vi올림픽 토토ble range will be demonstrated.
