Core-shell excitonic nanoparticles emulating plasmon like-properties

Plasmonic materials are well stablished and used in fields like biomedicine or energy harvesting due to their exceptional optical properties. One of the most interesting characteristics of plasmonic nanoparticles is their ability to confine light at the nanoscale. Nevertheless, such behaviour can also be found in some non-metallic materials as in organic-excitonic materials based on J-aggregates. Herein, we evaluate the synthetic route to obtain colloidal dispersions of excitonic core-shell nanoparticles that can mimicking plasmonic behaviour.
