eng Effect of incorporation of nickel or cobalt ions on the structure and physical properties of zinc-phosphate glasses Glasses containing 3d transition metal ions were found to exhibit interesting magneto-optical properties due to the distinct orbital configuration, various valences and coordination states. The aim of our work was to study the influence of nickel and cobalt, i.e. a typical transition metals, on the structure and some physico-chemical properties of zinc-phosphate glasses. The glasses of the system NiO-ZnO-P2O5 were prepared by the conventional melt–quenching technique in two compositional series formally expressed (in oxides): the first series (A) xNiO/CoO-(50-x)ZnO-50P2O5 and the second one (B) xNiO/CoO-(50-0.75x)ZnO-(50-0.25)P2O5. The Raman spectroscopy, 31P MAS NMR spectroscopy, magnetic susceptibility, UV-VIS-NIR spectroscopy and electron paramagnetic resonance were used to obtain information on their short as well as intermediate-range structure. Thermal properties of glasses were studied by thermomechanical analysis. phosphate glasses; 3d metals; structure; 31P MAS NMR
