| 摘 要： | A new empirical model to estimate the content of sp^3 in diamond-like carbon （DLC） films is presented, based on the conventional Raman spectra excited by 488nm or 514nm visible light for different carbons. It is found that bandwidth of the G peak is related to the sp^3 fraction. A wider bandwidth of the G peak shows a higher sp^3 fraction in DLC films.
