الملخص العربي
Films of polymer (polyvinyl alcohol (PVA)) doped with CuCl salt at different concentrations (2 and 10) wt% were prepared using casting technique. The optical properties of the films were studied after annealing. The transmission and absorption spectra have been recorded in the wavelength range of (300-1100) nm. The effect of annealing on the optical properties for (PVA- CuCl) films with different concentrations (2 and 10) wt% of copper chloride salt shows that the transmittance decreased after annealing for all the films. The optical constants (absorption coefficient, refractive index, extinction coefficient, real and imaginary parts of dielectric constant) for all the films are affected by annealing. The energy gap (Eg) of all the films decreased after annealing.
