In the present work, PVA and various concentrations of FeCl3 doped PVA polymer were prepared and optical studies like IR and UV/Visible analysis were carried out on them in solution form also the cast films were examined for their conductance. The variation of optical band gap of PVA polymer with the addition of Fe3+ transition metal ion has been determined by the Tauc plot method. It is found that the optical band gap and the transmittance of the polymer solutions being decreased with the increase in the concentration of Fe3+ ion, and thus obeys Beer's Law. This is supported by conductivity obtained for these polymers and FT-IR spectra which shows the stretching of the various bonds of the polymer due to the addition of transition metal (Fe3+) ions.
