Hydrogenated and H-free diamond-like carbon (DLC) samples were prepared and 244 nm and 514 nm Raman spectra were collected and analyzed. Correlations between Raman spectra and sp(3) content of DLC samples from this and previous studies have been analyzed. The dispersion rate of the G peak is shown to correlate linearly with the sp(3) content of hydrogenated DLC samples, while the full-width-half-maximum of the G peak is shown to correlate nonlinearly with the sp(3) content of H-free DLC samples. Quantitative relations are presented for measuring the sp(3) content of both hydrogenated and H-free DLC. (C) 2010 Elsevier B.V. All rights reserved.
