Abstract

In this paper an InGaN/GaN MQW based blue LED has been successfully fabricated and tested. It requires a very low bias voltage of 2.8 V and the emission wavelength has been observed to be ~ 455 nm. It can be converted to a white LED by coating with yellowish phosphor usually made of ceriumdoped yttrium aluminum garnet (Ce3+: YAG). In near future it has potential application in various type of illumination and may replace the present lighting accessories like incandescent bulbs, vehicle light, tube lights etc. White LED’s are 10 to 50% more energy efficient, low power consumption of the order of mW and able to reduce our operating cost up to 90%.
