Abstract

Time-resolved Förster energy transfer from single halide-terminated nanocrystals with n-butylamine ligands (0.6 nm) onto two-dimensional graphene is measured with time-correlated single-photon counting. Remarkable 4× reduction in spontaneous emission is observed (237 MHz) and modified LDOS.
