Even with the new systems now available to study, internal conversion has yet to catch up to more nuanced applications. Take for example an electromagnetic field: while fluctuations and their effects are a key feature of quantum electrodynamics , very little is understood as per a fields interaction with the internal conversion mechanism. Couto & Kowalewski note that the tuning of cavity strength and resonance frequencies can alter the exciton dynamics of a chromophore. Huang and co-workers were able to determine a relation between the coupling strength of a plexciton (hybrid emitter-nanocavity pseudo-particle) and internal conversion, however only in terms of a specific decay channel. Bennett and co-workers highlighted how internal conversion in a given system could be altered by using a cavity. Ulusoy and co-workers examined how light-matter coupling could be used to modify known photochemical properties via polaritons (photon strongly coupled to electric dipole), and found that direct excitation of the upper polaritonic states could allow for a pathway to drastically slow internal conversion rates. However, beyond that, there is minimal work on the subject matter, as the state of the art continues to evolve.
