Abstract

Abstract: We demonstrate the rapid spectral shift of the plasmon resonant peak from a single silver nanoparticle deposited on a dielectric-coated silver film in air under white light illumination. This shift occurs within several hours of white light illumination under the resonant condition of the metal–insulator–metal structure formed below the particle and is attributed to promoted sulfurization at the surface of the single silver nanoparticle resulting from the plasmonic heat generation. This thermal plasmonic effect will play a crucial role in the stability of plasmonic devices in the future.
