Comprehensive study on the effect of Gd2O3 NPs on elastic properties of zinc borotellurite glass system using non-destructive ultrasonic technique

Quaternary Gd2O3 NPs doped zinc borotellurite (TeO2-B2O3-ZnO-Gd2O3 NPs) glass system were fabricated using conventional melt-quenching method with composition {[(TeO2)70(B2O3)30]70(ZnO)30}1-x(Gd2O3 NPs)x (x = 1.0, 2.0, 3.0, 4.0 and 5.0 mol%). The physical, structural and elastic properties of the gl...
