Abstract A new empirical model to estimate the content of sp³in 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 sp³ fraction. A wider bandwidth of the G peak shows a higher sp³ fraction in DLC films.
