Abstract
The Nd3+-doped lithium-zinc-phosphate glasses were prepared by means of conventional melt quenching method. X-ray Diffraction results were confirmed the glassy nature of the studied glasses. The physical parameters such as the density, molar volume, ion concentration, polaron radius, inter-ionic distance and field strength were calculated using different formulae. The absorption, transmittance and reflectance spectra of glasses were recorded in the wavelength range 190–1200nm. Bonding of Nd3+ ions with surrounding ligands is found to be covalent. Dispersion parameters such as: single oscillator energy, dispersion energy, the ratio of carrier concentration to the electron effective mass and the lattice dielectric constant are determined. Electronic polarizability of the oxide ion and optical basicity of these glasses are calculated from the values of optical band gap. Effects of doping Nd2O3 on these properties are investigated and interpreted.
