| Abstract | ||
| Films of pure (PVA) and (PVA) doped by (KMnO4) have been prepared using casting method. We have studied the effect of(KMnO4) dopant on the optical properties of a polymer poly(vinyl alcohol) (PVA). Optical band energy gap (Eg) is estimated using (UV-VIS) spectra and it was classified as indirect allowed transition . Optical transmittance, Absorptance , Absorption coefficient , real and imaginary part of dielectric constant and Skin depth are investigated and correlated with the action of doping process. | ||
