Manifestation of the silver nanoparticles incorporated into the poly vinyl alcohol matrices

Electrical and optical properties of the silver nanoparticles (Ag NPs) incorporated into the polyvinyl alcohol (PVA) matrices were investigated as a function of Ag NPs. The intensities of FT-Raman bands have a maximum corresponding to the Ag NP amount about 3.6 mg.. The PVA doped with different amounts of Ag NPs shows UV-Visible peaks, were red shifted by Ag NPs increase, while their intensities according well with the FT-Raman spectra. The UV-Visible spectra for the 3.6 mg Ag NPs doped in PVA presented a small red shift and band intensity decrease by increasing temperature. C 2006 Springer Science + Business Media, Inc.
