a PL spectra (excited at 570 nm) of (6,5) SWCNT samples containing 1 mM p-iodoaniline and irradiated with UV light for different times under ambient (left panel) and argon (right panel) conditions. b Emission intensity vs UV irradiation time for (6,5) samples containing 1 mM p-iodoaniline. The black curve shows the pristine emission (E11). The green curve represents E11* defect-state emission obtained under ambient conditions. The red and blue curves show defect-state emission E11* and E11**, respectively (obtained under argon conditions). c Prolonged UV irradiation causes slight red-shifts of defect-state emission.
