PVA doped FeCl3 have been deposited utilizing casting technique. Absorption
spectrum was registered in the wavelengths (300-900 nm) utilizing UV-Visible
spectrophotometer. Optical constants behavior such as, absorbance, absorption coefficient, and
skin depth were studied. It was found these parameters were increased as Fe content increase.
While the extinction coefficient and optical conductivity was decreased. The energy gap of PVAFe films were decreased from 4 eV for the PVA film to 3.5 eV for the PVA: 4 % Fe film.
