Paper Abstract

Cerium activated strontium-magnesium orthophosphate phosphors could be used in the manufacture of erithermal or copy machine lamps. Under short wave UV radiation, cerium activated strontium-magnesium orthophosphate exhibits strong UV luminescence with emission maximum at 370-380 nm. The luminescent emission depends on both host matrix composition and activator amount. Samples of (Formula available in paper):Ce phosphors with variable composition, i.e., different Mg/Sr ratio and variable cerium content, were synthesized and characterized in order to establish the optimum host lattice composition and cerium concentration.
