Paper Abstract

Cerium activated strontium-magnesium orthophosphate phosphor exhibits strong UV luminescence whereas cerium-manganese activated phosphor shows pink luminescence. These phosphors could be used for the manufacture of eritemal or copy machine lamps and for fluorescent lamps for luminous signs, respectively. Samples of (Sr1- xMgx)3(PO4)2:Ce and (Sr1- xMgx)3(PO4)2:Ce, Mn phosphors with variable compositions were synthesized and characterized. Crystalline structure and luminescence properties were determined and discussed in order to establish the optimum synthesis conditions for phosphor preparation.
