英文摘要	The electron momentum density and sp(2)/sp(3) ratio of carbon materials in the thermal transformation of detonation nanodiamonds (nd) into carbon nano-onions are systematically studied by electron energy-loss spectroscopy (eels). electron energy-loss near-edge structures of the carbon k-ionization in the electron energy-loss spectroscopy are measured to determine the sp(2) content of the nd-derived samples. we use the method developed by titantah and lamoen, which is based on the ability to isolate the pi* spectrum and has been shown to give reliable and accurate results. compton profiles (cps) of the nd-derived carbon materials are obtained by performing eels on the electron compton scattering region. the amplitude of the cps at zero momentum increases with increasing annealing temperature above 500 degrees c. the dramatic changes occur in the temperature range of 900-1300 degrees c, which indicates that the graphitization process mainly occurs in this annealing temperature region. our results complement the previous work on the thermal transformation of nd-derived carbon onions and provide deeper insight into the evolution of the electronic properties in the graphitization process.
