| 摘要 |
The present invention is related to solid state light emitting diodes (LEDs), photodetector/photovoltaic devices, displays, applications and methods for making the same. As demonstrated experimentally, the LEDs, as disclosed herein, have high light emission efficiency, high contrast, high brightness, low ambient light reflection, low light glare, and a tunable display viewing angle. The same LED disclosed here can be used as high efficiency displays and high efficiency photovoltaic device or photodetectors. This means that the same device, where used in array form, can be used as the display (LED operation mode) and power supply (photovoltaic device mode) and camera (photodetector and imaging mode). |
