Description
Summary:Sm3+ doped Sodium Lithium Phosphate glasses are prepared by conventional melt quenching method and the effect of Sm3+ ions on the physical and optical properties of these glasses has been studied and reported. The obtained X-ray diffraction patterns confirm the amorphous nature of the glass samples. The densities of the samples are measured by the Archimedes method, and the physical properties like molar volume, oxygen packing density, interionic distance, field strength, rare earth ion concentration and polaron radius have been calculated using appropriate formulae. The optical absorption spectra of the prepared glasses in the UV-Visible region (wavelength 200-1100nm) are recorded at room temperature to study the optical properties of the glasses. The optical energy bandgap values are determined from Tauc plots. The refractive index values of all the prepared glass samples are calculated, and these values are used to determine the corresponding molar refraction, the molecular polarizability of oxide ions, dielectric constant, reflection loss and metallization criterion of all the glass samples using appropriate formulae.
