Synthesis and Spectral Characteristics of CoO mixed ZnO-Bi2O3-B2O3 Glasses

Abstract

The conventional melt-quench process synthesized bismuth borate glasses containing ZnO and CoO. CoO is introduced up to a maximum of 0.8 mol% by replacing boric acid. All the prepared samples were tested by x-ray diffraction and scanning electron microscopy techniques. Characterization methods confirm the non-crystalline behavior of samples. The density of the samples was found to increase while molar volume diminishes against the content of cobalt oxide. UV-visible spectra have shown the necessary bands of divalent and trivalent cobalt ions. Infrared spectra display all characteristic vibrational bands of different molecular groups. Increasing structural degree of disorder is evidenced from the analyses of results, and details are presented.
