摘要

The near-field distribution of plasmonic coupling effect in gold nanoparticle pairs was directly investigated by a nearfield scanning optical microscope (NSOM) in the fiber-collection mode. NOSM images show that the localized plasmonic coupling and the electromagnetic field distribution of nanoparticle pairs are systematically influenced by the interparticle space and axial direction of incident polarization. This observation can facilitate the understanding of localized hot spots in surface-enhanced Raman spectroscopy in the near field and can be used as a guideline for fabricating specific nanostructures in controlling the spatial distribution of surface plasmon (SP) modes for ultrasensitive sensors or photonic devices.
