Abstract
Glasses doped with transition metal ions become now of high interest because of their various applications in both science and technology. Accordingly the study of these glasses has drown the interest of most solid-state physicists, chemists and material science researchers. Also, the change of the physical properties of these glasses is directly connected to their structural transformations. On other hand, IR spectroscopy was found to be an effective tool for investigating glass structure. In addition ME spectroscopic analysis was established now to be a good technique which was successfully used long time age to investigate the hyperfine structure of glasses containing iron or any Mossbauer isotope. However, in this work the structure and the physico-chemical properties of some boro-phosphate glasses containing iron and zinc oxides were thoroughly investigated, under the effect of replacing P2O5 by B2O3 in the glass networks.
