| Abstract: | The infrared absorption spectra of Manganese-doped Iron
borate glasses (X=0,10,15,20&30 mol% MnO) have been investigated to find
out the role played by Manganese on the structure of these glasses. MnO was
gradually introduced to replace Fe2O3 in the series of
manganese doped iron borate glasses containing 60% B2O3 .
The structural changes induced were consistent with Mn2O3
formulation and were inferred by monitoring the I.R. spectra of these glasses
in the range 200-4000 cm-1 by KBr Technique. The similar ionic radii
of Fe3+ and Mn3+ cause no structural changes in either
series as observed from infrared spectroscopy, which show that the Fe3+
ions concentration at B-site is replaced by Mn3+ ions. Mössbauer
Technique was applied to study the effect of manganese doping at the Fe site
for all the samples. |
