Abstract
Barium tellurite (Ba-Te) base glass with and without europium ions have been synthesized by customary melting and quenching method. XRD is done for the verification of the nature of prepared specimens. DSC of the samples was done to determine the glass transition temperature. Density (ρ) of specimens was calculated by Archimedes’s principle. Other physical parameters as oxygen packing density (OPD), Europium ion concentration (CL) in the specimen, molar volume (Vm), intermolecular distance Ri, Polaron radius Rp, europium ion concentration and Molar index of refraction Rm, were computed. In order to study the optical characteristics of the specimens, for instance, coefficient of absorption, forbidden energy gap (Eg), refractive index, and Urbach Energy (E), UV-visible absorption characterizations of Ba-Te glasses was performed in the range of 340-1000 nm. PL characterization has performed for photoluminescence study.
