“…46 Such effect has been invoked to explain the spectral shifts between near-field probe and far-field spectra 47 and has already been reported theoretically for extinction and scattering. 48 These expressions also predict that the magnitude of the shift increases with the amount of dissipation, which is in agreement with the fact that a shift is measured between EELS and CL only on large particles lying on a carbon foil.…”

Plasmon modes of the exact same individual gold nanoprisms are investigated through combined nanometer-resolved electron energy-loss spectroscopy (EELS) and cathodoluminescence (CL) measurements. We show that CL only probes the radiative modes, in contrast to EELS, which additionally reveals dark modes. The combination of both techniques on the same particles thus provides complementary information and also demonstrates that although the radiative modes give rise to very similar spatial distributions when probed by EELS or CL, their resonant energies appear to be different. We trace this phenomenon back to plasmon dissipation, which affects in different ways the plasmon signatures probed by these techniques. Our experiments are in agreement with electromagnetic numerical simulations and can be further interpreted within the framework of a quasistatic analytical model. We therefore demonstrate that CL and EELS are closely related to optical scattering and extinction, respectively, with the addition of nanometer spatial resolution.

“…The experimental technique allowing for measuring quantitatively the optical scattering and extinction cross-section spectra has also been described in [1] and shall not be repeated here. As expected from theory [11], scattering and extinction do not exhibit exactly the same resonance positions [1]. The fact that we have been and are able to resolve these small differences can be taken as an indicator of the quality of the technique and our data.…”

Using a rather large set of different individual metallic optical antennas, we compare directly measured electron energy-loss spectra with measured quantitative optical extinction and scattering cross-section spectra on the identical antennas. All antenna resonances lie near 1.4 µm wavelength. In contrast to other reports, we find identical resonance positions for electrons and photons to within the experimental errors. We discuss possible artifacts which can lead to seemingly different resonance positions in experiments. Our experimental results agree well with complete numerical calculations of both sorts of spectra.

Surface-Enhanced Infrared Spectroscopy Using Metal Oxide Plasmonic Antenna Arrays

et al. 2013

We successfully demonstrate surface enhanced infrared spectroscopy (SEIRS) using arrays of indium-tin oxide (ITO) plasmonic nanoantennas. The ITO antennas show a strongly reduced plasmon wavelength, which holds promise for ultracompact antenna arrays and extremely subwavelength metamaterials. The strong plasmon confinement and reduced antenna cross section allows ITO antennas to be integrated at extremely high densities with no loss in performance due to long-range transverse interactions.
