Ultrafast energy transfer between Graphene Oxide quantum dots and plasmons in strong coupling region

The optical nonlinearity of graphene oxide quantum dots (GOQDs) in the presence of plasmons is modified by resonant excitation of ultrashort laser pulses. The experimentally observed ultrafast Rabi oscillations in GOQDs/MNPs indicates coherent energy transfer between excitonic quantum emitters and plasmonic field in strong coupling regime. Our experimental measurements are consistent with the theoretical observations in quantum emitter-plasmon hybrid system¹.
