Mn2 activated green emitting SrAL12O19 luminiscent material

摘要

A SrAl₁₂O₁₉ green luminescent material is doped with Mn² activator ions and at least one trivalent rare earth sensitizer ion species. Preferably, the material contains four rare earth ions: Ce³, Pr³, Gd³ and Tb³. Optionally, a portion of the aluminum may be substituted with magnesium. The material may be used as a display device or lamp phosphor or as an X-ray diagnostic or laser scintillator.
