ABSTRACT:
A phosphor capable of being kept from being affected by oxygen during production thereof, carrying out luminescence due to excitation by electrons, selectively realizing various luminous colors depending on selection of starting materials and exhibiting satisfactory luminance and life characteristics. The phosphor is represented by a chemical formula Ga.sub.1-x In.sub.x N:A (0.ltoreq.x<0.8, A.dbd.Zn or Mg) and prepared by mixing starting materials containing at least an oxygen-free gallium compound and an oxygen-free doping substance to prepare a mixture and heating the mixture in a nitrogen-containing atmosphere.
