To elucidate the possibility of quantitatively analyzing sp2-hybridized carbon (sp2-C) and sp3-C in carbon materials using total-electron-yield (TEY) X-ray absorption spectra (XAS) in the C K region, we measured the TEY-XAS of mixtures of multi-walled carbon nanotubes or carbon black as sp2-C sources and diamond as an sp3-C source. The measured relationship between the π*/σ* peak intensity ratio in the C K TEY-XAS and the weight (atomic)% of sp2-C can be successfully explained by the summed TEY of the sp2-C and sp3-C components and considering the TEY efficiency of sp3-C relative to sp2-C, k. However, the experimentally determined k values show that TEY of the sp3-C is much smaller than that of sp2-C by about one order of magnitude, even depending on the chemical form and/or electronic properties of individual carbon components. This suggests that further evaluation of the TEY efficiency is necessary prior to the quantitative sp2/sp3 analysis of carbon materials using the TEY-XAS.
