Ag-CuO/rGO/PVDF nanocomposite synthesized via simple method as a broadband non-linear optical material for optronic applications

Ag-CuO/rGO nanoparticles were synthesized successfully using the low-cost co-precipitation method. The obtained nanoparticles were characterized to be used as a special filler of the PVDF polymer in different concentrations [1, 1.5, 2, 2.5]%wt. The Ag-CuO/rGO/PVDF composite was characterized and optically investigated. The optical and non-linear optical properties of the Ag-CuO/rGO/PVDF composite were superior in that it outperformed many of recently published works that discussed PVDF composites’ optical parameters values and compete for these values with lower ratios of the used nanoparticles. The Ag-CuO/rGO nanoparticles enhanced the absorption coefficient, refractive index, optical conductivity, dielectric constant, and the non-linear optical parameters intensities of the PVDF polymer. This enhancement occurred in a broad-spectrum range from 235 to 800 nm. However, Ag-CuO/rGO nanoparticles reduce the optical band gap energy to be 1.9 eV with nanoparticles concentration of 2.5%wt. The obtained results strongly support the use of Ag-CuO/rGo/PVDF composite in optotronic devices applications.
