Abstract

In Ref. 1 and at the Spring 2022 ECS B03 Symposium on Carbon Nanotubes, we reported on the long-range energy transfer of excitons from (6,5) to (7,5) carbon nanotubes across an insulating barrier in an optical microcavity, mediated by moderate and strong exciton-photon polariton coupling and measured via two-dimensional, white-light spectroscopy. This talk will present on the alternative use of nanotube-C60 photovoltaic devices embedded in microcavities to quantify the efficiency of this long-range energy transfer and the factors that affect it.[1] Energy cascades in donor-acceptor exciton-polaritons observed by ultrafast two-dimensional white-light spectroscopy, M.
