Synthesis and Structural Properties of Sm3+ doped Sodium Lithium zinc Lead Borate Glasses

Abstract

Abstract Sodium lithium zinc-lead borate glasses co-activated with Sm3+ ion were prepared by melt and quenching method. The glass composition regarding to (65 – x)B2O3 : 5ZnO : 5Li2O : 15 Na2O : 10PbO: x Sm2O3 chemical formula is synthesized with x = 0.0; 0.05; 0.1; 0.5; 1.0; 2.0 and 4.0 mol.%. These samples which are labeled as Sm_0.0; Sm_0.05; Sm_0.1; Sm_0.5; Sm_1.0; Sm_2.0 and Sm_4.0 respectively. The structural characteristic was investigated and analyzed by using the FTIR and XRD. Moreover, physics properties such as molar weight, density, molar volume, refractive index, etc were calculated with the standard equations. From the measurement and calculation, the density was found to increase slightly by showing linear trends with Sm2O3 content in the glass network structure. It was happened due to the compactness level of glass structure and geometrical arrangement have modified in the glass network. The molar volume of the glass samples also gradually increases from 28.185 cm3/mol to 29.613 cm3/mol. From the FTIR and XRD analysis can be confirmed that the present samples are amorphous without the presence of the crystalline peak.
