Abstract
In this paper, a systematic spectroscopic analysis on silver–polyvinyl alcohol ( Ag /PVA) nanocomposite thin films is reported. Ag /PVA nanocomposite thin films fabricated by thermal annealing process are shown to exhibit a strong localized surface plasmon resonance (LSPR) at wavelength around 400 nm. The effects of different fabricating parameters on the absorbance and spectral position of LSPR are also investigated. The particle sizes calculated from Mie light scattering theory are found to agree with the values obtained from SEM characterization.
