Evaluation and Analyzing the Linear Optical Properties of Polymer/Al-Ag-ZnO Nanocomposites

The manuscript explores the effects of incorporating inorganic–organic nanoparticles into the matrices of polystyrene, poly (methyl methacrylate), and polyvinyl alcohol on their linear optical properties. Transmission electron microscopy technique (TEM) is used for analyzing the morphology of aluminum (Al), silver (Ag), and zinc oxide (ZnO) nanoparticles. The chemical composition of the samples was analyzed using Fourier transform infrared spectroscopy (FTIR), while their optical properties were evaluated using UV–Vis spectroscopy. The synthesis of nanoparticles exhibits a clear spherical morphology. The reflectance (R), extinction coefficient (K), linear refractive index (n), real (ε^r) and imaginary (ε^𝐢) parts of dielectric constants, and optical conductivity (σ) were evaluated and analyzed. All the parameters given above were observed to be affected by increasing concentrations of Al, Ag, and ZnO. The synthesis of nanocomposites as foil has significant promise for the fabrication of highly efficient optoelectronic devices.
