Paper Abstract

Diamond-like carbon (DLC) films (a-C:H) were implanted by 140 keV and 110 keV Ar ion beams. The characteristics of the implanted films decreased dramatically under a dose of 2 X 1016 Ar/cm2. IR spectra and optical gap Epot were measured. It was found that the SP2 and SP3 components decreased due to the loss of hydrogen during implantation, and the ratio of components SP2 bonds to SP3 bonds increased with the ion dose. And the optical gap Epot decreased from 1.46 eV to 0.83 eV. The hydrogen (bonded and unbonded) contents in the films were measured with the nuclear resonant reaction 1H (19F,) 16O. It is shown that hydrogen plays an important role in affecting some properties of DLC films.
