Özet
Structural features of hafnium or cerium doped iron borophosphate glasses have been studied by Raman and EPR spectroscopies. Hf and Ce are introduced into the composition as surrogates for Pu. Raman spectrum of Hf and Ce free base iron phosphate glass indicate that the glass network consisted mainly of Q1 units with contributions from Q2 units. The general features observed for base glass are maintained in the Raman spectra of Hf/Ce containing glasses with some modifications with increasing Ce/Hf content in the composition. The EPR spectra of Hf and Ce containing glasses show different features. Superparamagnetic domains were highlighted through EPR for all CeO2 containing glasses.
