Abstract
Glasses of composition Fe2O3•Li2O•B2O5•Bi2O3 in the system doped with cobalt ion were prepared by quenching technique [1]. Heat-treatment of the parent glasses was performed at 400 C for 4 and6 h. The glass structure evolution was examined by FT-IR spectroscopy analysis. The FT-IR data propose for these glasses and heat-treated glass network structures mainly built by: di-, tri-, tetra-, penta-and ortho-borate groups.
