Abstract

We studied the spatial characteristics of plasmon modes in single noble metal nanoparticles (gold nanorods and others) by linear and non-linear optical methods combined with near-field optical microscopy. Near-field images of the nanoparticles obtained show peculiar spatial patterns, and are attributed to spatial characteristics of plasmon modes (wavefunctions) excited. The images are strongly dependent on observed wavelength, and from the dependence we obtained dispersion relation of the plasmon. We also studied ultrafast dynamics of single gold nanorods by near-field time-resolved technique. We found that energy dissipation processes are strongly dependent on the internal position of the nanoparticle.
