The fabrication and spectroscopic characterization of varying content of Y3+ doped bismuth titanate borosilicate glasses by the melt quenching technique are described. The nature of glass system composition was established using XRD spectra analysis. The manufactured glasses’ molar volume reduced while their density and refractive index continued to increase. UV transmission, absorption, polarizability, and basicity are all found to be highly sensitive to Y2O3 content. The optical bandgap and Urbach energy have been discussed in detail. It was observed that, as Y2O3 increase, the optical bandgap increases, while Urbach energy decreases. Based on the results of the calculations of molar Refractivity, molar polarization, polarizability, optical basicity and dispersion, the fabricated glasses are thought to be very semi-covalent. Metallization of the present glasses are increased.
