Abstract
Abstract
Samarium zinc sodium phosphate glasses doped by different Er2O3 concentrations were prepared using a conventional melt quenching technique. The structural properties due to the influence of Er+3 ions on the presented glass network were investigated. XRD pattern confirms samples amorphousity. Surface morphology using SEM proved the non-crystallinity and the homogeneity of the samples. The elemental composition using EDAX analysis gave an acceptable mass percentage of the constituent's elements. FTIR revealed the formation of Non-Bridging oxygen (NBO). The measured density, molar volume, ion concentration, interatomic distance, polaron radius and field strength have been studied with respect to the concentration of Er+3.
