| Abstract: | The chemical and energy structures of highly fluoridated fullerene films have been investigated. Analysis of the complex structure
of carbon 1s spectra showed the presence of C-F and C-F2 fragments as well as nonfluoridated carbon atoms with an overwhelming quantity
of C-F bonds. The band gap in fluoridated-fullerene and its films was estimated to be 8.0 eV and energy loss on an interband
transition at 11 eV was also observed. Comparison of the valence-band spectra of the experimental samples showed that the
valence band of fluoridated fullerenes is divided into anionic and cationic parts (similarly to alkali-halide crystals) and
suggests that fluoridated fullerenes possess the corresponding properties, making it possible to find new materials with wide
practical applications.
