Abstract

The one dimensional array structures built from spherical silver nanoparticles that produce remarkable narrow plasmon resonance spectra upon irradiation with light were discussed. The study was carried out by using electrodynamics calculations. Variations of the extinction energy, plasmon resonance wavelength and width particle size, array structure, interparticle distance and polarization direction were also examined. The results show that the sharp resonance arises from cancellation between the single particle width and the imaginary part of the radiative dipolar interaction.
