Synthesis and Optical Characterization of Nd3+ doped TeO2-PbO-Li2O
Abstract: Glass based on
Nd3+-doped TeO2-PbO-Li2O has successfully been made by melt quenching technique
and their thermal parameters have been determined using Differential Thermal
Analyzer (DTA). The glass is then nucleated and/or growth by controlled heat
treatment at slightly below the crystallization temperature. The X-ray
diffraction (XRD) technique is used to estimate the nano-crystallite size.
Meanwhile, the optical characterization has been determined using the
Photoluminescence Spectroscopy. It is found out that the crystallite size is
about 20 nm and very much depending on the heat-treatment time. Meanwhile, the
intensity of the luminescence spectra is very much depending on the
concentration of the dopant.
