Fabrication of LED Based on III-V Nitride and its Applications (<Special Issue> Where are the Materials for Ultraviolet Devices and Where are These Going ?)

Abstract

III-V nitride semiconductors are useful for LED with colors covering ultraviolet, blue through green. Luminescence of these LEDs has high luminosity and high purity of color, and, therefore, many applications such as full colordisplay and backlight of LCD module were realized by us ing these LEDs. Short wavelength LED is used for an exciter of phosphors that can generate any color including white. The air purifier is also developed by combining short wavelength LED and the photo-catalyst such as TiOx.
