| Popis: | The interaction between the excitonic J-band of J-aggregate molecules and localized plasmonic resonances supported by metallic structures can be large enough to reach the regime of strong coupling, giving rise to two hybridized modes [1, 2]. The new hybrid system is often characterized in extinction measurements, where the strong coupling results in an avoided crossing of the two modes as the detuning of the plasmonic mode with respect to the excitonic transition is changed. In principle, the photoluminescence (PL) signal should also exhibit a characteristic anti-crossing signature, but, so far, it has been challenging to identify it in experiments [2, 3]. |
