Abstract :
The excitation of surface plasmons on individual silver nanowires is studied by high-resolution electron energy loss spectroscopy in a transmission electron microscope, and the results are compared to ensemble optical spectra. The transverse and longitudinal modes of these nanostructures were selectively resolved, confirming the plasmon peak shift versus nanowire length.
