Temporal evolution of a single CNT.
The data were collected by focusing laser beam on a single CNT and collecting the emission at 10 s intervals. Colors changing from black to red indicate increasing emission intensity. (a) 20 min temporal evolution as a function of photon energy. (b) Individual spectra taken from the temporal data shown in (a). (c) Plot of linewidth as a function of time evolution in (a).
