ABSTRACT
Polarization dependences of Rayleigh and surface-enhanced Raman scattering (SERS) were measured for individual Ag nanoparticles on which Rhodamine 6G molecules were adsorbed. It was found that the polarization dependencies of surface plasmon bands generated by the aggregation of SERS active Ag particles are well synchronous to those of Raman bands. This result strongly supports the recent electromagnetic SERS model that amplified electric field at particle junctions localized in the aggregate gives rise to SERS. © 2003 American Institute of Physics.
