Effect of lithium addition on thermal and optical properties of zinc-tellurite glass

► (80−x)TeO2-x Li2O-20ZnO) (0 ⩽ x ⩽ 10) glasses were prepared by melt quenching method. ► FTIR results revealed that the glassy matrix is composed of TeO3, TeO4 and ZnO4 units. ► Some physical properties as a function of Li2O content have been evaluated.
