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

Abstract

Abstract 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 3x1017, 6x1017, and 9x1017 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 6x1017 ions.cm− 2, the single oscillator energy Eo rises from 3.25 eV for the un-irradiated film to 3.89 eV and the dispersion energy Ed rises from 0.098 eV to 0.26 eV. Therefore, the results reveal that irradiated PVA/CuO composite are more applicable for optoelectronics.
