Abstract

The authors presented an experimental observation of the dynamically optical response of silver nanoparticle film. A 7nm-thicked sliver film was thermally deposited on an indium tin oxide glass substrate and that be annealed from room temperature to 300°C. The absorbance spectra and the dark-field micrograph of the silver nanoparticle film exhibited novel optical response, strongly dependent on the particle geometry, from the excitation of the localized surface plasmon. In particular, the peak wavelength and the maximum value of the absorbance and the exhibited color of the sample changed dramatically during the heating. A convenient and non-destructive technique to directly explore the substance in nanoscale has been achieved based on the optical analyses.
