Abstract

Surface plasmon coupling effects of isolated and collective Au nanoparticle arrays are investigated through the optical transmission spectroscopy and near-field scanning optical microscope (NSOM). Nanoparticle arrays with different collective degrees are fabricated by the nanosphere lithography and self-assembling technique. The absorption wavelength of collective nanoparticle array at surface plasmon resonance orients to longer wavelengths due to the particularly strong localized electromagnetic field exists in the gap of nanoparticle pairs. Besides, results manifest that localized surface plasmon coupling not only depends on the inter-particle distance but also relates to the photon-plasmon resonance.
