(a) PL spectra of PTM-functionalized and (b) ArBr-functionalized (6,5) SWCNTs before and after irradiation. (c) PL lifetime components extracted from biexponential fits to the decay traces. (d) EPR spectra recorded for the dispersions used in the PL experiments before and after irradiation. Note that the initial EPR signal intensity is relatively low, because dilute dispersions were employed for the optical characterization.
