Abstract

Electron energy loss spectroscopy combined with spectral imaging in a transmission electron microscope is used to probe and map the energy distribution of the optical-frequency surface plasmons of coupled gold nanorods. Local field enhancement and spectral shift of the surface plasmon modes is observed when two nanoparticles are electromagnetically coupled.
