Title: Time-resolved energy transfer from single chloride-terminated nanocrystals to graphene

Abstract

We examine the time-resolved resonance energy transfer of excitons from single n-butyl aminebound, chloride-terminated nanocrystals to two-dimensional graphene through time-correlated single photon counting. The radiative biexponential lifetime kinetics and blinking statistics of the individual surface-modified nanocrystal elucidate the non-radiative decay channels. Blinking modification as well as a 4x reduction in spontaneous emission were observed with the short chloride and n-butylamine ligands, probing the energy transfer pathways for the development of graphene-nanocrystal nanophotonic devices.
