Near-field imaging of surface-enhanced Raman active sites in aggregated gold nanoparticles

Imura K, Okamoto H, Hossain MK, Kitajima M

We observed near-field images of aggregates of gold nanospheres, by detecting TPI-PL from gold and Raman scattering from Rhodamine 6G adsorbed oil the nanoparticles. The results were analyzed in relation to the localized Raman active site (hot Spot) of surface-enhanced Raman scattering,.
