| 简介 |
A phosphor with oxide crystal containing at least first metal ions and second metal ions as a base is provided. The first metal ions include at least one type of valence III metal ions selected from the group consisting of aluminium, gallium, vanadium, scandium, antimony and indium. The valence III metal ions are partially substituted with at least one type of valence III rare earth ions qualified as a luminous body. The second metal ions are metal ions other than valence II metal ions. The phosphor has the luminescent quantum efficiency improved since the inversion symmetry of the crystal field is intentionally destroyed to increase the transition intensity. |
