Energy cascades in donor-acceptor exciton-polaritons observed by ultrafast two-dimensional white-light spectroscopy
Abstract
Exciton-polaritons are hybridized light-matter states that exhibit intriguing phenomena that are unobserved in purely excitonic states. Here, the authors elucidate the photophysical mechanism of polariton-assisted long-range energy transfer in carbon nanotubes using two-dimensional white-light spectroscopy and quantum calculations.
