Elastic properties of TeO2–ZnO–Ag2O doped with Nd2O3

A series of Neodymium doped zinc-tellurite glasses incorporated with Ag2O with chemical composition {[(TeO2)0.70(ZnO) 0.30] (1-X)Nd2O3(X)}(0.99)Ag2O(0.01), x = 0.01, 0.02, 0.03, 0.04 and 0.05, were synthesized by applying the melt-quenching technique. The FTIR analysis confirmed the presence of only...
