Optical properties for (Polystyrene-zinc oxide) nanocomposite for optoelectronic application

Abstract

It was essential to investigate the features of overlapping nanocomposites because of the significance they have in the fields of science, industry, electricity, and medicine. As a result, it garnered a lot of attention and led a lot of scientists and researchers in the direction of studying the features of nanocomposite. Investigations have been conducted into the fabrication of (polystyrene (PS)-zinc oxide (ZnO)) nanocomposites and the examination of the optical characteristics of these nanocomposites for use in optoelectronic applications. Various concentrations for PS polymer & ZnO NPs were used in the fabrication of the nanocomposites using the solution casting process. The results of the experiments performed on (PS-ZnO) nanocomposites appear that each of the absorbance (A), absorption coefficient (α), extinction coefficient (K), refractive index (n), real and imaginary dielectric constants (εr & εi ), and optical conductivity (σopt ) of polystyrene increase by increasing ZnO NPs concentrations. On other hand, the transmittance (T) and energy gap (E_g ) decrease by increasing ZnO NPs concentrations. Nanocomposites made of zinc oxide have a high absorption in the ultraviolet spectrum.
