(color online) (a) PL of a single gold nanorod at four orientations of excitation and detection polarizations.[45] (b) SEM image, (c) DF scattering, and (d) PL spectra of gold nanoflowers under excitation of 532 nm and 633 nm lasers with different polarization angles.[46] (e) Excitation-wavelength dependent partially depolarized PL spectra from the dolmen-like plasmonic nanostructure under four excitation-collection configurations.[47]
