Using the traditional melt quenching procedure under carefully regulated atmospheric circumstances, the glass system 60TeO2-(25-x)Bi2O3-15B2O3-xSrCl2 with mole fractions x=5, 10, 15, and 20 was created. Differential scanning calorimetry (DSC) was used to calculate the glass transition temperature (Tg), and it was shown that the Tg value increased as the amount of SrCl2 in the glass system increased. This rise in Tg is probably due to a greater number of bridging oxygen (BO) atoms, indicating the increase in glass thermal stability. FTIR and Raman spectral data have been deconvoluted for estimating the peak, whereas each deconvoluted peak exhibits numerous peaks. The present glass system's IR and Raman spectra analysis revealed that SrCl2 acts as a network modifier in the form of Sr-O bond. TeO2 is made up of a variety of structural components, including TeO3 trigonal pyramidal, TeO4 trigonal bipyramidal, and TeO3+1. BiO6 octahedral structural units define bismuth (Bi2O3), which modifies networks. Both BO3 trigonal and BO4 tetrahedral structural units of B2O3 can be found in the glass system.
