摘要
用Mg k_xΧ射线得到的全碳分子C_60/C_70和石墨的芯级C_18谱、价带(YB)谱和俄歇电子(CKLL)谱。结果表明,C_60/C_70中碳原子的杂化态主要是sP^2,但存在着一定的sP^3.使用XAES可以表征C_60/C_70和石墨,且是一种灵敏而有效的方法。
The X-ray photoelectron spectra (XPS) of C_18, the valence spectra and Auger electron spectra (CKLL) of C_60/C_70 fullerenes and graphite obtained with Mg Ka radiation are reported and discussed in this paper. The results show that the hybridization of the carbon atoms in C_60/C_70 fullerenes is esse- ntially sp^2 state with some sp^2 character. The XAES is probably a sensitive and effective mothod for characterization of C_60/C_70 fullerenes and graphite.
