Abstract

Holmium doped bismuth-Tellurite glasses of composition 85TeO₂ - (15- x Bi₂O₃) - x Ho₂O₃, (x=0.1, 0.2, 0.3, 0.4 and 0.5 mol %) were prepared using the conventional melt quenching method. For the optical applications, it is very important and essential to find the optical and physical properties of prepared glasses. The influence of Ho³⁺ ions on the optical properties of Bismuth - Tellurite glasses was studied through UV absorption spectra. In the UV-visible region of wavelength 200-1100 nm, absorption spectra were recorded at the room temperature. The physical properties such as refractive index, molar refraction and polarizability of prepared set of glass have been calculated by using Lorentz-Lorentz relations. By the absorption edge studies, the values of optical bandgap energies have been evaluated. With respect to small variation of holmium (Ho³⁺) ion concentration the non-linear variations of the above optical parameters were discussed.
