Book excerpt: Abstract : The resonance behaviors of local surface plasmon resonance in Au monomer and dimer are characterized systemically by electron energy loss spectroscopy in a scanning transmission electron microscope. The measured absorption range is about 20 nm larger than the physical size of the Au nanoparticles and the resonance peak energy shows a red shift when the electron beam passes of the nanoparticles. The Au dimer displays similar behaviors. Numerical simulation also reproduces those experimental results.
