Eu2+ luminescence in novel Sr3.5Mg0.5Si3O8Cl4 and Ba3.5Mg0.5Si3O8Cl4 phosphors is reported in this paper. These were synthesized by combustion method at 5500C furnace temperature .The prepared phosphors shows PL emission spectra at 445 nm ,due to 4f65d1→ 4f7 transition of Eu2+ ions by monitoring excitation at 358 nm for Sr and Ba host lattice. Phase purity was checked by using XRD-pattern. The prepared phosphors have potential applications for solid-state lighting purpose. Copyright © 2011 VBRI press.
