Effect of CuO Doped Polyvinyl Alcohol on the Structural and Optical Properties of PVA Films

The effect of copper oxide doped in PVA on the structural and optical properties of composite films is studied experimentally. Samples are PVA films of 20±1 µm thickness doped with different studied using X – ray diffraction. Using the transmittance of samples, the effect of doped and their concentration on optical parameters of PVA films include absorption and others parameters. Results show the band gap energy of samples is decreased. Keywords : PVA films, doping, optical properties
