| Abstract | ||
| Films of pure (PVA) and (PVA) doped by (KMnO4) have been prepared using casting method. Transmission and absorption spectra have been recorded in the wavelength range (300-900) nm . the study of the optical properties of the deposited films have done in order to identify the possible change that happen to the (PVA) films due to doping. The study of the optical parameters gives an indication that the doping affected all the studied parameters like, absorbance , reflectance, refractive index , extinction coefficient. | ||
