The study of ternary alkali bismuth borate glasses doped with various 3d transition metals (TM) has been carried out to give more information on the oxidation states of 3d transition metal ions doped in a host of ternary alkali bismuth borate glasses. The compositional variation in density and molar volume has been investigated in terms of the structural modification that takes place in the glass matrix on introducing various 3d TM in these glasses. Analysis of FTIR spectra shows the peak positions (cm-1) at around 700 cm-1 corresponds to B-O-B bending while the broad peak at 900-1150 cm-1 result due to combined contributions of stretching vibrations of B-O bonds in BO3 units from pyro-orthoborate groups and stretching vibrations of B-O bonds in tetrahedral BO4 units in tri-borate, tetraborate and penta-borate groups. Another broad peak around 1300-1500 cm-1 attributes to vibrations attached to large segments of borate network.
