FeCl 3 was used as a source of Fe that added to the PVA films. PVA-Fe films were
prepared by casting method. The UV-Visible spectrophotometer used to record the
absorbance spectrum in the range of 300-900 nm. The absorbance decreased with the
increasing of Fe in the PVA films. The absorption coefficient increased with the
increasing of Fe content, while the extinction coefficient, refractive index and optical
conductivity are decreased. The optical conductivity decreased from 4 eV for PVA film
to 3.3 eV for PVA-3% Fe films.
