Effect of Sm3+ concentration on physical properties of magnesium tellurite glasses containing silver nanoparticles

A series of tellurite (TeO2) glass containing samarium (Sm2O3) and silver nanoparticles with a composition of (89.6-x)TeO2-10MgO-(x)Sm2O3-0.4AgCl with 0.2 ≤ x ≤ 1.0 mol% have been synthesized by a conventional melt quenching technique. The X-ray diffraction pattern verified the amorphous nature of g...
