The dynamics of excitons in individual semiconducting single-walled
carbon nanotubes was studied using time-resolved photoluminescence (PL)
spectroscopy. The PL decay from tubes of the same (n,m) type was found
to be monoexponential, however, with lifetimes varying between less than
20 and 200 ps from tube to tube. Competition of nonradiative decay of
excitons is facilitated by a thermally activated process, most likely a
transition to a low-lying optically inactive trap state that is promoted
by a low-frequency phonon mode.
