Effect of low energy ion beam irradiation on the structural and optical properties of flexible PVA/CuO nano composite films

The solution casting production process was used to synthesis the composite PVA/CuO that is consisting of copper oxide nanoparticle (CuONP) with polyvinyl alcohol (PVA) for use in optoelectronic. The PVA/CuO composite were then irradiated with argon fluences of 3x10 17 , 6x10 17 , and 9x10 17 ions.cm − 2 by cold cathode ion source. The XRD, FTIR, and UV/Vis are employed to investigate the structural, functional group, and optical impacts of PVA/CuO. In addition, the dispersion properties of the investigated films were calculated using the Wemple and Di-Domenico method, which led to the determination of various optical parameters. Pure and irradiated films were estimated for their optical susceptibility and refractive index. At the fluence of 6x10 17 ions.cm − 2 , the single oscillator energy E o rises from 3.25 eV for the un-irradiated film to 3.89 eV and the dispersion energy E d rises from 0.098 eV to 0.26 eV. Therefore, the results reveal that irradiated PVA/CuO composite are more applicable for optoelectronics.
