This manuscript focuses on investigating how the ratio of glass modifier to former (m/f) affects the properties of silver borotellurite glass. Upon preparing the glasses with the formula Ag2SO4-TeO2-0.6B2O3, spectroscopic and dielectric analysis was performed on the samples. Crystalline phase is present in samples with an m/f ratio of more than 0.8, while amorphous phase is proven by the absence of prominent peaks in XRD spectra for samples with a m/f ratio of less than 0.8. The densities of the samples became greater with the addition of the various modifiers to the mixture. The mixing caused values for the optical band gap to drop while increasing values for the Urbach energy. The FTIR spectra made the discovery that the structure of the glass had a number of borate and tellurite groups. On the basis of conductivity measurements, an investigation of the change in AC, DC, and activation energy with modifier to former ratio is carried out. The results of the dielectric investigations suggested that an increase in the m/f ratio of Ag + could potentially lead to an improvement in the ionic conductivity of the material.
