Physical and optical study of alkali and alkaline earth metals based phosphate glasses

Abstract

 The glass samples with chemical composition (mol%) of 10Na2O-10SrO-10Gd2O3-70P2O5, 15Na2O-10SrO-10Gd2O3-65P2O5, 10Na2O-15SrO-10Gd2O3-65P2O5, and 15Na2O-15SrO-10Gd2O3-65P2O5 which are referred as 1NSP, 2NSP, 3NSP and 4NSP, respectively, in this article, were prepared by the melt quenching technique. The obtained glass samples show 66% transmission. The density of the samples was calculated by using the Archimedes principle using water as immersion liquid at room temperature, the molar volume, the refractive index and UV-Vis spectroscopy are the other characterizations used in this work to evaluate our samples’ properties. The density of the samples is increase with the increasing amount of sodium and strontium oxides, while the molar volume decrease for the increasing amount of these oxides. The refractive index of the prepared glass samples increase from 1NSP to 4NSP.
