| Résumé : |
In this investigation, nanostructured films comprising polyvinyl alcohol (PVA)/polyethylene glycol (PEG) blended with indium oxide (In2O3) nanoparticles were fabricated using a casting technique. The study focused on examining the impact of varying the ratios of PVA/PEG blend and In2O3 nanoparticle content on the optical properties of these nanostructures. Optical assessments were conducted across a spectrum ranging from 220 nm to 820 nm. It was observed that an increase in In2O3 nanoparticle concentration resulted in elevated absorbance levels in the PVA/PEG matrix, particularly within the ultraviolet spectrum, while simultaneously causing a decrease in transmittance. This effect was attributed to the interaction between the polymer matrix and the In2O3 nanoparticles, leading to altered electronic and photonic interactions within the material. A notable reduction in the energy band gap was also recorded with increasing In2O3 content, suggesting enhanced electron mobility and photon interaction within the nanostructures. These findings underscore the potential of In2O3-doped PVA/PEG films in optoelectronic applications, particularly in fields requiring controlled optical properties such as photonics and advanced optical systems. The improved optical parameters, specifically in terms of absorbance and band gap manipulation, highlight the versatility of these nanostructures in various optoelectronic applications. |
