The sp2 ratio is crucial as it provides insight into the hybridization state, structure, and electronic properties of hydrogen-free and hydrogen-containing diamond-like carbon (DLC) films, influencing the properties and application of DLC films. Near-Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy has been reported to deliver a high-resolution sp2 ratio with specific constraints in hydrogen-containing. To address this limitation, Soft X-ray Emission Spectroscopy (SXES) plays a novel role in the reflective chemical states of DLC films to quantify the sp2 ratio. In this research, SXES is employed to quantify the sp2 ratio in a variety of various DLC films, addressing the limitation associated with NEXAFS in determining the sp2 ratio hydrogen-containing DLC films.
