Samarium zinc sodium phosphate glasses doped by different Er2O3 concentrations were prepared using conventional melt quenching technique. The structural properties due to the influence of Er+3 ions on the presented glass network were investigated. The X-ray diffraction (XRD) patterns confirm the amorphousity of the samples.Surface morphology and elemental composition of glasses were studied using scanning electron microscope (SEM) accompanying withElectron Dispersive spectra (EDX).The measured density , Molar volume,ion concentration, interatomic distance, polaron radius and field strength had been studied with respect to the concentration of Er+3. Fourier Transform Infrared Spectroscopy (FTIR) results showed that Q1 and Q2 were the mean structural units of these glasses and revealed the formation of Non-Bridging oxygen (NBO).
