Graphene-based nanomaterials offer superior properties especially in optical performance. The existence of oxygen functionalized group in graphene active layers is beneficial to enhance the optical properties of current tellurite glass. In this work, two series of glasses denoted as ZBTEr (uncoated) and ZBTEr-GO (coated) were successfully prepared using melt-quenching and low-cost spray coating techniques. X-ray diffraction analysis was done on both glass series and confirmed the amorphous structural arrangement in the glass system. Morphological study was investigated by using Scanning Electron Microscopy (SEM) and revealed the distribution of graphene layers on the glass surface. The UV-Vis spectroscopy was carried out and several absorption bands were determined for both series of glasses. The computation of oxide ion polarizability and optical basicity were investigated based on Lorentz-Lorentz equation. The oxide ion polarizability and optical basicity for ZBTEr-GO (coated) glasses were found higher than ZBTEr (uncoated) glasses due to the existence of sp2 graphitic attached on the oxygenic functional groups in GO layers. The metallization criterion values for ZBTEr-GO (coated) glasses were found decreased and tend to be more metallic. Hence, the deposition of graphene layers on the tellurite glasses offer a new strategy to improve the current telecommunication devices.
