Abstract

It was found by photoelectron spectroscopy that C₆₀ molecules undergo polymerization and oxidation upon ultraviolet light irradiation. It was observed that UV light is more effective than visible light in the photo-induced transformation, suggesting that the process is initiated by excitation of electrons beyond the energy gap between the HOMO and the LUMO bands of C₆₀. It was also found that oxygen molecules absorbed in solid C₆₀ play a key role in the photo-induced oxidation process.
