| 英文摘要 | a systematic investigation on singlet oxygen (o-2(a(1)delta)) photoluminescence (pl) from fullerene (c-60) solutions by using a pulsed nd: yag laser at 532 nm was reported. the results show that the o-2(a(1)delta) pl intensity first increases linearly, then declines fast, and eventually tends to level off with the increase of pump energy, while decreases monotonically with increasing irradiation time. the latter can evidently be attributed to the formation of photoinduced o-2(a(1)delta) quenchers, which was directly confirmed by the remarkable decrease of o-2(a(1)delta) lifetime with increasing irradiation time. also, we further demonstrated that the o-2(a(1)delta) quencher should be c60o via electrospray ionization-mass spectrometry (esi-ms) and a kinetic analysis on the formation rate of the o-2(a(1)delta) quenchers in irradiated c-60 solutions. on this basis, the above pump-energy dependence of o-2(a(1)delta) pl was also rationalized kinetically. with the increase of pump energy, the initial linear increase is exactly attributable to the linear increase of o-2(a(1)delta) concentration, while the following drop should result from the fast formation of photoinduced o-2(a(1)delta) quenchers and the eventual smooth variation is evidently related to the inverse saturated absorption effect of c-60.
