Investigations of physical and structural properties of calcium alumino silicate glasses doped with samarium (III) oxides

Abstract

We synthesized and investigated the physical and structural properties of calcium alumino-silicate glasses systems: (60-x)SiO2-2.5Al2O3-10CaO-17Na2O-10K2O-0.5Sb2O3-xSm2O3. The samples were prepared using melt quenching method. Density was measured using Archimedess principle, and the physical properties such as the ion concentrations, interatomic distance, polaron radius, and field strength were calculated. The density, the calculated ion concentrations, and field strength increased while the interatomic distance and polaron radius decreased with increasing of Sm2O3 contents. The structure of the glasses was characterized using the Fourier transform infrared spectrometer. The FTIR result showed that the change in the network structures of these glasses depends on the concentration of Sm2O3.
