Enhanced optical, morphological, dielectric, and conductivity properties of gold nanoparticles doped with PVA/CMC blend as an application in organoelectronic devices

Stevia rebaudiana plant leaves were used for biosynthesis of gold nanoparticles (AuNPs). Transmission electron microscope images showed various shapes and sizes AuNPs. Various amounts AuNPs added to polyvinyl alcohol/carboxymethylcellulose (PVA/CMC, 40/60) via the casting method. The X-ray diffraction (XRD) spectrum pure blend shows amorphous nature blend. FTIR spectra interaction between PVA/CMC ultra-violet visible emerging new peak surface plasmon resonance filled samples. scanning bright spots on sample’s surface, which was attributed AC conductivity exhibited enhancement after addition nanoparticles. ?? ?? reduced with increasing frequency due direction dipoles applied electric field. Because mobile charges inside polymeric backbone, higher values observed at low frequencies. tan? increased an increase in concentration decrease high frequency, as expected.
