    • Abstract


      Sulphate glasses prepared from K2SO4−ZnSO4 system were doped with Fe2+, Co2+, Ni2+ and Cu2+ ions in the form of their sulphates. The spectra in the visible region indicated octahedral coordination of these ions. The spectral features remain unaffected in the entire composition range. Hence the zinc ion in these binary sulphate glasses is likely to retain octahedral coordination in the entire glass forming compositions.
