Focusing of local electromagnetic fields in plasmonic materials produces enhanced signals and enables control of light propagation for spectroscopy and energy transfer applications. We are creating plasmonic architectures with structural control in order to tailor this optical antenna-like behavior. Two approaches will be described: 1) preparation of organized multi-nanoparticle assemblies based on a novel and […]
