Cyan LED luminous efficiency increased by 30% source technology was developed

The South Korean Ministry of science and Technology Education (Executive: Ann byong man 21 published) by the South Korean domestic research group will luminous efficiency of the second generation lighting source InGaN blue LED had the highest increase of more than 30% successful source technology development.

In the Kwangju science and Technology Institute researcher Zheng Wenxi Zheng Jianyong, led by Kim stannanes and Zheng Hyun doctoral researcher, the research results developed by metallographic scene doctoral participation by the scientific journals in the field of materials science and Engineering (Advanced Functional Materials, IF = 6.808) is selected as the 9 version of the spotlight, and is published as the cover paper.

The development of the technology compared with the former LED, not low electrical characteristics, depending on the optical waveguide phenomenon of zinc oxide nano rod, the luminous efficiency is increased more than 30%.

Professor Zheng Jianyong said: "the research results from the material fee or fee will be relatively simple engineering side of zinc oxide optical waveguide effect (ZnO) rod at low temperature, will not affect the LED electrode structure and make growth, is the luminous efficiency across the source of technical improvement, future research etc. with the integration of nanotechnology, will be $110 billion in 2015 and the interests of the world LED lighting market".
