Effect of SO2−4 on the Structure and Luminescence Properties of Manganese-doped Sulfophosphate Glasses

Manganese-doped sulfophosphate glasses(P_2O_5-ZnO-ZnSO_4-Na_2O) were synthesized by traditional melting-quenching method.The structure and luminescence properties of the glasses with varying SO_4~(2-) content were studied.The results revealed that a broad emission band of Mn~(2+) from 500 to 750 nm excited by a 409 nm laser was observed.With the introduction of SO~(2+),the ligand field around Mn~(2+) was affected,resulting in the increasing of the luminescence intensity and full width at half maximum(FWHM) of Mn~(2+) emission.
