18 Experimental Setup SEM image Octahedral gold monomer and dimer are placed in an evanescent field produced by total internal reflection of white light in a glass prism. The scattering image of monomer and dimer was recorded using a digital camera and was spectrally analyzed by polarization-selective spectroscopy.
19 Scattering Spectra from Au Nanocrystal Dimers s = 125 nm s = 125 nm scattering intensity ( a.u.) s = 105 nm s = 85 nm s = 65 nm s = 45 nm s = 25 nm scattering intensity ( a.u.) s = 105 nm s = 85 nm s = 65 nm s = 45 nm s = 25 nm wavelength ( nm ) wavelength ( nm )
20 Using TM-polarized incident light, the evanescent field is elliptically polarized in the x-z plane, and produces z- and x-polarized evanescent intensities in a 9:1 intensity ratio. Evanescent wave Dimer separation (edge to edge) =25 nm to 125 nm Projected length of octahedral nanoparticle = 200 nm Dimer distance (center to center) =225 nm to 325 nm 0.5λ Daniel Axelrod et al., Ann.

Near field coupling needs higher spatial resolution and is difficult to be achieved. near-field effect Far field Experiment couplingin far field coupling (gap distance/ diameter) LinLin Zhao, K.

24 Summary The dimer separation can be precisely controlled by using a nanomanipulator. The plasmon resonance energies of single near-fieldcoupled nanocrystal dimers can be tuned with nm spectral resolution. We can measure both the in-phase ( bright ) and antiphase ( dark ) coupled plasmon modes by polarizationselective total internal reflection microscopy and spectroscopy.
