Polarizability and optical basicity of Er3+ ions doped tellurite based glasses

The refractive indices (n) and densities (ρ) of {[ (TeO2)0.70 (B2O3)0.30]1-x (ZnO)x}1-y (Er3O2)y glasses with y = 0.00, y = 0.005, y = 0.01, y = 0.02, y = 0.03, y = 0.04, y = 0.05 were measured at room temperature. The theoretical value of average electronic polarizabilty and oxide ion polarizabilit...
