Abstract
An inorganic powder uses a UV solid light source applied for the UV LEDs, in which an inorganic powder is based on the inorganic powder of n-silicate group II elements, and its ingredients have valence 2 ions, such as Eu, Sm, Yband Dy, valence 3 ions Ce, Tband/or Eu. The chemical formula of the components is MeLnSiO:TR:TR, and x=0.0-0.2, y=0.0-0.1. A main structure thereof is a hexagonal crystal structure. When the indium gallium nitride and gallium nitride based allomorphous semiconductor short wave UV light is used under conditions of excitement, the multiple band white light can be obtained.
