Strong excitonic-plasmonic coupling in hybrid system of metal nanoparticles and J-aggregates of organic dye

We present our recent results on the development and characterization of hybrid sytems consisting of plasmonic nanostructures and organic dye molecules in a J-aggregate state.

The measured spectra exhibit a strongly suppressed signal at wavelengths which correspond to the J-aggregate band, which is indicative of strong interaction between the plasmonic and excitonic systems.
