摘要：
Gold nanoparticles (AuNPs) were successfully synthesized using Chenopodium murale (C. murale) leaf extract. Polymeric matrix of polyethylene oxide (PEO)/polyvinyl pyrrolidone (PVP) doped with different concentrations of AuNPs were prepared via casting method. Fourier transform infrared spectroscopy (FT-IR) was used to retrace variations in the main structural building units within polymeric nanocomposites before and after exposing to different irradiation times of UV lamp type C. FT-IR analysis reveals an induced changes in chemical structure attributed to the doping level and irradiation times. Ultraviolet/visible optical absorption spectra (UV/vis.) confirm the presence of AuNPs in the nano scale as a consequence of observing band at 420 nm attributed to the surface plasmon resonance (SPR) of AuNPs. Optical parameters (i.e. optical energy gap Eg, refractive index n) for prepared polymeric nanocomposite before and after irradiation process were calculated and interpreted.
