摘要
The photopolymerization of C60 and Li@C60 films was investigated by means of optical second-harmonic generation. The films were deposited under ultra-high-vacuum conditions and irradiated in situ with an Ar+ laser at 514 nm. The second harmonic generated by a Nd:YAG laser working at 1064 nm was monitored after different steps of irradiation. Photopolymerization was observed after very low irradiation doses, of the order of 1020 photons/cm2, and confirmed with infrared absorption spectroscopy. Similar kinetics for C60 and Li@C60 were observed. The measurements give evidence for photopolymerization of the endohedral fullerene Li@C60.
