Luminescent material doped with trivalent and/or divalent ions |
| 摘要 |
<p>A Y(P,V)O4:Eu<3+> red emitting phosphor is doped with at least one of a trivalent rare earth ion excluding Eu and a divalent metal ion to improve the lumen maintenance of the phosphor. The preferred material is the Y(P,V)O4:Eu<3+> phosphor doped with trivalent Tb<3+> ions and divalent Mg<2+> ions. <IMAGE></p> |
