Abstract
The conventional rapid melt quenching method was used to prepare neodymium doped alumina lead germanate glasses. Different physical parameters of these glass materials such as density, molar volume, electronegativity, optical basicity and refractive index were calculated. Structural, optical, electrical and dielectric properties of neodymium doped GeO2-PbO-PbF2 glasses with increasing concentration of Al2O3 were studied and reported. X-ray diffraction studies confirmed that the prepared samples were non-crystalline in nature. Surface morphology revealed that the glass materials prepared have similar surface topography. The optical absorption edge observed at 610.5 nm for neodymium glass materials shifted to higher wavelength region with increasing concentration of Al2O3 up to 1.0 mol%, beyond the concentration shift towards shorter wavelength region. The intensity of the luminescence peak was observed around 1090 nm corresponding to 4F3/2 - 4I11/2 transition. The observed functional values of analyzed CIE chromaticity from the luminescence spectra were suggested that the prepared samples were used as white photoemission sources.
