摘要：

Raman spectra were measured of highly fluorinated graphite samples prepared at room temperature, 380 and 515 degreesC. CxF prepared at room temperature showed a novel downshifted band at 1555-1542 cm(-1) along with G band at 1593-1583 cm(-1). Similar behavior is also observed for samples prepared at 380 and 515 degreesC at early stages of fluorination, after which the Raman shifts completely disappeared. Raman spectra as well as X-ray diffraction (XRD) analysis suggest that graphite fluorides, (CF)(n) and (C2F)(n) are formed via fluorine-intercalated phase with planar graphene layers.
