摘要：
Polyvinyl Alcohol - Nickel Oxide composite have been prepared by solution cast technique with different filler concentrations (0.25, 0.5) wt%. The obtained films have the thickness of the order of 50 mu m. X-Ray diffraction confirms the retention of NiO nanoparticles in PVA polymer matrix. In optical study the absorption spectra of the UV radiation were studied in the wavelength range 200-800 nm and the results were analyzed in terms of absorption formula for non-crystalline materials. The decrease in the optical band gap with concentrations suggests creation of new levels in the band gap.
