摘要：

Results of optical studies on oxygen-doped, alkali-metal(M)-doped and photopolymerized solid C60 films are reported. Results of Raman scattering studies of MxC60 films are presented, but discussion is focused on recent Raman scattering studies of superconducting Rb3C60 films (T(c) almost-equal-to 28 K) from T = 300 to 9 K. The effects of the exposure of C60 to light and/or oxygen are also presented. If pristine C60 is exposed at T = 300 K to visible or UV light, a photoinduced polymerization of the structure is obtained, which is consistent with results from laser desorption mass spectroscopy and optical spectroscopy. If oxygen is also present, the photoinduced polymerization is suppressed, and the oxygen is observed to diffuse about 2000 angstrom in about 1 h, eventually leading to oxidation of the structure.
