Sm3+-doped zinc magnesium sulfophosphate glasses were synthesized by conventional melt-quench technique. FTIR spectra were recorded to investigate the structural properties of the glasses. Differential thermal analysis (DTA) was confirmed the thermal stability of studied glass samples. UV-Vis-NIR absorption spectroscopy was obtained and J-O analysis was determined to derive the spectroscopic properties of Sm3+ doped zinc magnesium sulfophosphate glasses. Spontaneous radiative transition probabilities (A), radiative lifetimes (tau(R)), branching ratios (beta) for the excited (4)G(5/2) transition level were calculated and discussed. Thirteen absorption peaks were exhibited in the UV-Vis-NIR spectra. Emission spectra exhibited four significant peaks located at 561, 596, 643 and 703 nm which are assigned to the (4)G(5/2)-> H-6(5/2), (4)G(5/2)-> H-6(7/2), (4)G(5/2 ->)(6)H(9/2,) and (4)G(5/2)-> H-6(11/2) transitions, respectively and the intensities of all bands were quenched by addition of ZnSO4 ions contents. The results revealed that the PMS-ZS10 glass matrix has the higher values of branching ratios and emission cross-sections for (4)G(5/2)-> H-6(7/2) transition. It is observed that the Sm3+-doped zinc magnesium sulfophosphate glass can be promise candidate for lasers in the visible range.
