Investigation of Plasmonic Resonances in Mismatched Gold Nanocone Dimers
Source abstract
Abstract
The plasmonic properties of two closely adjacent gold nanocones of different sizes have been investigated. The plasmon modes of the first nanocone couple with the plasmon modes of the second one due to which a broad peak and a narrow peak emerges in the extinction spectrum, which can be categorized as bright and dark plasmon modes. The destructive interference of the two modes results in a sharp Fano dip in the spectrum. Several configurations of the conical nanodimer have been considered, which suggests that the plasmon coupling in the nanocone dimer is not only dependent on the interparticle distance and size of the nanoparticles but also on their spatial arrangement. The localized high near-field energy in the nanodimer can be used for surface-enhanced Raman spectroscopy applications.
