Device with Mn2+ activated green emitting SrAl12O19 luminescent material
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.
