Abstract

At present, the light efficiency of the high-power white LED has reached 250 lm/W in the industry. The light efficiency reported in the laboratory has exceeded 300 lm/W. The innovation of LED technology and application of LEDs have far exceeded expectations. However, the luminous efficiency of the traditional planar LED with InGaN/GaN multiple quantum well structure is difficult to rise significantly due to some inherent problems. At the same time, the light efficiency is still far away from the theoretical limit of 400 lm/W. In addition, with the demand of some special applications, some new LED technologies such as nanorod LEDs, quantum dot LEDs, polarized LEDs, etc., have been explored. The exploration of the growth, preparation and application of these new LED structures not only contribute to the research of basic physics but also to solve the bottleneck problem in the development of semiconductor lighting by improving the material and device performance and by approaching the theoretical limit of LED lighting. Thus, it has important research value.
