Abstract

The plasmonic properties of Au nanorods (NRs) have been investigated theoretically and experimentally, a system that is of high current interest in relation to various nanophotonics applications. The non-aligned NRs arrays were formed by a seed-mediated growth method that relies on the reduction of metal salt by a weak reduction agent in the presence of preformed metallic seed nanoparticles. We applied the finite-element method to calculations of absorption spectra from gold NRs supported in an aqueous solution. Comparison to experimentally measured spectra is found in a good agreement.
