Abstract
Polarization-dependent inelastic optical scattering (IOS) of individual Ag nanorods and nanoparticles are studied by confocal imaging. Stronger IOS is observed at two ends of the nanorod with laser polarizing parallel to the rod long axis while the IOS images of Ag nanoparticles elongate along laser polarization direction. The correlation between the far-field IOS image and near-field spatial distributions of the nanostructures′ electric field can be obtained. The IOS imaging is demonstrated to be an effective technique to study the optical properties of metal nanostructures, which also provides information for their applications in surface-enhanced Raman scattering.
