摘要：

Core-level photoabsorption has been used to determine the sp(2) and sp(3) bonding content of nanocrystalline diamond thin films grown using C-60 Or CH4 precursors. The C(ls) absorption spectra show clear bulk diamond excitonic and sp(3) features with little evidence of sp(2) bonding, while the Raman spectra measured from these same films are ambiguous and indeterminate. This result can be attributed to the local structure (near-neighbor bonding) sensitivity of core-level photoabsorption that is insensitive to domain size, unlike Raman spectroscopy.
