FTIR Analysis of $Bi_2O_3-B_2O_3-Fe_2O_3$ Glass System Doped with $Nd_2O_3$

In the present work $Bi_2O_3-B_2O_3-Fe_2O_3$ glasses have been prepared via melt quenching method. The composition has been fixed to 60 mol% B2O3, 20 mol% $Bi_2O_3$ and 20 mol % $Fe_2O_3$ which is a stable glass forming composition. In these glasses, $Nd_2O_3$ has been doped in exchange of $Fe_2O_3$ concentration. FTIR studies have been performed in these glasses to examine the distribution of different borate and bismuth structural groups. The effect of iron and neodymium on these distributions has been examined
