Fabrication of LED Based on III-V Nitride and its Applications

Abstract

ABSTRACTShort wavelength LED (TG Purple) based on III-V nitride semiconductors is established in addition to blue and green. This short wavelength LED is realized by adjusting “Indium” chemical content of the well layer. Light output power of “TG Purple” is high and FWHM is narrow. “TG Purple” is applied to light source of white LED. Combination of “TG Purple” and various phosphors can generate white light with high luminous intensity and good color rendering. “TG Purple” is also applied to light source of air-purifier. This air-purifier was equipped in a car and several applications of this system are widely utilized in room air conditioners and refrigerators.
