In this contribution, MnO2 doped borate glass matrix with ratios 0.0, 0.5, 1.0, 1.5 and 2.0 wt% were prepared utilizing melting method. The structural characterization of these glass samples was performed via X- ray diffraction measurements. Optical absorption analyses within the 200–1000 nm wavelength range were performed to characterize the samples. The direct and indirect optical energy gaps (Eopt) decreased however Urbach energy (EU) increased with increasing MnO2 concentration. The refractive index, and optical conductivity values are observed to increase with increasing MnO2 concentration. FTIR spectra of borate glass doped with 0.0, 0.5, 1.0, 1.5 and 2.0 wt% MnO2 revealed the presence of absorption bands due to Mn2+.
