The Optical Properties of Copper Oxide Nanoparticles with (Polyvinyl Alcohol-Polyethylene Glycol) Blend


The optical constants and optical energy gap of (PVA-PEG-CuO) nano-composite films have been studied in the present paper. The nano-composite films was prepared by casting technicality, where, (PVA-PEG) blends used as matrix while the Copper oxide nanoparticles were (0, 2, 4, 6, 8) wt% as a filler. The present study is aimed to modification of the optical properties of blends with different concentrations of (CuO) nanoparticles and for achieves a new class of material. The absorption and transmission spectra have been recorded at the wavelength range 220-800 nm. The experimental results illustrate that the absorbance of pure blend was increased with increase of Copper oxide concentrations and vice versa with transmission. On the other hand, the optical constants and optical energy gap were changed with the addition of Copper oxide nanoparticles concentrations.
