摘要

The present study aims to boost of morphological, microstructure and optical properties of futuristic polystyrene (PS)/ silica (SiO2)/cadmium sulphide (CdS) nanosystem to be functional in a variety of promising optical and electronics applications. The microstructure and optical properties of PS/SiO2-CdS nanostructures were investigated. The structure properties of PS/SiO2-CdS nanostructures included: optical microscope (OM) and FTIR. The results of optical characteristics for PS/SiO2-CdS nanostructures indicate that the absorbance (A), absorption coefficient (α), extinction coefficient (k), refractive index (n), real (ε1) and imaginary (ε2) parts of dielectric constant, and optical conductivity (σ) of PS were increased, while energy band gap (Eg) and transmittance (T) were decreased with a rise in SiO2-CdS nanoparticles content. The PS absorption was enhanced about 46.3% at λ = 320 nm with rising SiO2-CdS nanoparticles content of 2.8%. The Eg of PS/SiO2-CdS nanostructures ranged between 3.35 eV and 3.63 eV. The n values ranged between 2.1 and 2.6 at λ = 500 nm with growing SiO2-CdS nanoparticles content of 2.8%. These performances made the of PS/SiO2-CdS nanostructures are multifunctional nanosystem for futuristic optoelectronic fields. Finally, the results of investigated properties confirmed to the PS/SiO2-CdS nanostructures are promising hybrid nanosystem to utilize in numerous optical and electronics applications.
