N2 - The influence of Eu3+ ions on the Optical properties of Boro Tellurite Glasses of (70-x) B2O3-15TeO2-10Na2O- 5PbO-xEu2O3 with x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5 mol% glasses were prepared by conventional melt quenching method and their physical and optical properties were investigated by using UV absorption spectra, which was recorded at room temperature in the UV-visible region of wavelength 200-1100 nm. By the absorption edge studies, the values of optical bandgap energies have been evaluated. The direct and indirect bandgap values ranges between 3.362 to 3.650 eV and 2.011 to 2.863 eV respectively. The refractive index, molar refraction and polarizability of oxide ions have been calculated by using Lorentz-Lorentz relations. The refractive index and molar refraction values were ranges from 2.241 to 2.358 and 76.147 to 79.915 cm3 respectively. The non-linear variations of the above optical parameters were discussed with respect to small variation of europium (Eu3+) ion concentration.
