Abstract

We clarified the relationship between near-field optical properties and the local structure in monolayer assembly of gold nanoparticles by using scanning near-field optical microscopy (SNOM) and scanning electron microscopy (SEM). The success of superposition of the SNOM image with the SEM image allows us to find that the intense electromagnetic field is localized at the rim part, especially the interstitial site of the dimerlike structure.
