摘要：
A luminescent phosphor composition having enhanced luminescent decay lifetime consists essentially of a non-stoichiometric tin and manganese coactivated alkaline earth orthophosphate represented by the formulaSr.sub.(3-v-w-x-y-z) .quadrature..sub.v Mg.sub.w Ca.sub.x (PO.sub.2).sub.4 :Sn.sub.y Mn.sub.zwhere0.001.ltoreq.v.ltoreq.0.050.180.ltoreq.w.ltoreq.0.350.ltoreq.x.ltoreq.0.080.015.ltoreq.y.ltoreq.0.050.0005.ltoreq.z.ltoreq.0.0905.An improved fluorescent lamp employing the disclosed phosphor is also described.
