Mapping localized plasmon modes in metal nanoparticles via electron energy loss spectroscopy and cathodoluminescence

Mapping localized plasmon modes in metal nanoparticles via electron energy loss spectroscopy and cathodoluminescence
Mapping localized plasmon modes in metal nanoparticles via electron energy loss spectroscopy and cathodoluminescence
In this work, the rich structure of SP modes localized in individual noble-metal nanoparticles prepared via lithography or colloidal chemistry is explored by optical spectroscopy, spatially resolved electron energy-loss spectroscopy (EELS) performed in a scanning transmission electron microscope (STEM), and by electron beam-induced radiation emission performed in a scanning electron microscope. Spectral features and spatially-resolved maps of SP modes collected for individual nanoparticles of different morphologies (rods, decahedra, prisms, and split-ring resonators) are shown to be in good agreement with theoretical STEM-EELS and optical excitation calculations obtained using the boundary element method based upon rigorous solution of Maxwell's equations.

Abstract

In this work, the rich structure of SP modes localized in individual noble-metal nanoparticles prepared via lithography or colloidal chemistry is explored by optical spectroscopy, spatially resolved electron energy-loss spectroscopy (EELS) performed in a scanning transmission electron microscope (STEM), and by electron beam-induced radiation emission performed in a scanning electron microscope. Spectral features and spatially-resolved maps of SP modes collected for individual nanoparticles of different morphologies (rods, decahedra, prisms, and split-ring resonators) are shown to be in good agreement with theoretical STEM-EELS and optical excitation calculations obtained using the boundary element method based upon rigorous solution of Maxwell's equations.
