The effect of modifier oxide on the structural and optical properties of Sm3+ doped tellurofluoroborate glasses with the chemical composition (50–x)B2O3+xCaCO3+30TeO2+ 10ZnO+9ZnF2+1Sm2O3 have been studied by varying B2O3 and CaCO3 content. The fundamental stretching vibrations in the prepared glasses were investigated using FTIR and Raman spectral analysis. The optical behavior and the excited state...
