Production and Ameliorating the Characteristics of (SiO2-CdS) Futuristic Nanoceramic Doped Optical Material for Flexible Nanoelectronics Applications

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 (E_g) 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 E_g 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.
