摘要
Irradiation effect in three carbon allotropes C60, diamond and highly oriented pyrolytic graphite （HOPG） induced by 170keV B ions, mainly including the process of the damage creation, is investigated by means of Raman spectroscopy technique. The differences on irradiation sensitivity and structural stability for C60, HOPG and diamond are compared. The analysis results indicate that C60 is the most sensitive for B ions irradiation, diamond is the second one and the structure of HOPG is cross sections σ of C60, diamond and HOPG deduced from 1.31 × 10^-15 cm^2, respectively. the most stable under B ion irradiation. The damage the Raman spectra are 7.78 × 10^-15, 6.38 × 10^-15 and1.31 x 10-15 cm^2, respectively.
