چکیده انگلیسی
Three groups of strong fluorescence peaks of C60, centered at 440, 575 and 700Â nm, are observed in the supersaturated C60-pyridine solution, and the onsite fluorescence spectra of this C60-pyridine system in the first and second electrochemistry reduction processes are obtained for the first time. The results indicate that the fluorescence peaks centered at 440Â nm originate from C60 molecules dissolved in supersaturated C60-pyridine solution, while fluorescence bands centered at 575 and 700Â nm are emitted from undissolved C60. It is also proved that a strong charge transfer interaction, which is significant for the symmetry increase of C60n-, as well as the formation of a transmission channel of energy, occurs between C60n- and pyridine, as is supported by surface-enhanced Raman scattering (SERS) spectra as well.
