摘要：

C60 films simultaneously exposed at T = 300 K to oxygen and visible-ultraviolet light are found to exhibit rapid diffusion of oxygen into the deep bulk of the film. The diffusion rate is found to be approximately 10 times faster in the presence of light. Vibrational and optical absorption spectroscopy indicate that the photoassisted reaction of O2 with solid C60 involves two coupled reactions: (i) the photoassisted diffusion of molecular oxygen into solid C60 and (ii) oxidation of C60.
