摘要:
The plasma-enhanced chemical vapor deposition system was used to grow amorphous hydrogenated carbon films deposited on silicon substrates. Extracts of the films were obtained by treatment with boiling cyclohexane solvent. The absorption spectra of these extracts showed the existence of small quantities of fullerenes. Using the molar extinction coefficient ofC60in cyclohexane, the mass of fullerenes in the films was estimated to be about 0.019 mg.C60induced fluorescence quenching of anthracene was also observed. Additional evidence for the presence of fullerenes was based on their capability to accelerate the photo-oxidation of anthracene through the generation of singlet oxygen with a high quantum yield under ultraviolet irradiation. ©1997 American Institute of Physics.
