Abstract

Interference patterns between photon excitation and plasmon mediated re-radiation are revealed on a metal nanoparticle basis. The plasmon-photon interaction is directly observed in the vicinity of silver nanoparticles through a near-field scanning optical microscope (NSOM). Isolated silver nanoparticles with different sizes on the pure quartz substrate are simultaneously fabricated through a high temperature annealing technique. Our results manifest that the correlation of phase-response and size-dependent optical enhancement can be further applied to control the spatial distribution of localized surface plasmon modes by means of framed nanostructures.
