Abstract
In this study we have prepared the specific composition 60B2O3–20CdO-5Al2O3-(15-x)ZnF2-xMoO3 (where x = 0, 0.5, 1, 1.5, 2) samples by using conventional Melt quenching method. The structural properties of the glass samples were characterized by using FTIR, Raman spectroscopy and X-Ray diffraction. The analysis of FTIR spectra divulges the existence of contrasting borate and aluminates units and also specifies the conversion of Mo6+ to Mo5+. As increasing of MoO3 concentration the density of glass materials is enhancing slightly. With increasing of MoO3, the decrease in the optical band gaps is observed in the studied compositions. This is happen due to the transformation of Mo6+ ions to Mo5+ ions will enhance of Non-Bridging oxygen concentration with increasing of MoO3. The analysis of Raman spectra suggested that BO4 units are transformed to BO3 units with increasing of MoO3 concentration. With increasing of BO3 units, the non-bridging oxygen’s levels will improve which in turn enhances the density of the compositions.
