Understanding the influence of rare earth ions in improving the structural and optical properties of inorganic glasses are the key issues. Er 3+-doped zinc boro-tellurite glasses with composition 30B 2O3-10ZnO-(60-x) TeO2-xEr2O 3 are prepared (x = 0, 0.5, 1, 1.5 and 2 mol%) using melt quenching tech...
