【Abstract】 The（0001）plane of the high oriented pyrolytic graphite（HOPG）was directly ablated by pulsed laser,and the products were recorded by mass spectrometry in situ.It is found that the relative abundances of C₆₀,C₇₀and other larger fullerenes were related to the ablating time──the regularity of the HOPG stirface,which was imaged by scanning tunneling microscopy （STM）.At the beginning of laser ablation,the（0001）plane contained enough six-membered rings,which mainly produced C₆₀and C₇₀.After laser ablation,many exposed platforms with no enough six-memberted rings,like amorphous carbon and aromatic compounds,were formed,which tended to form larger fullerenes.更多还原
