Synthesis of carbon nitride films by arc-heated atomic nitrogen beams assisted pulsed laser ablation

摘要

Carbon nitride films were synthesized by active atomic nitrogen beams intersecting pulsed laser plumes at the substrates without heating. The properties of the films were studied by Auger electron spectroscopy(AES), X-ray photoelectronspectroscopy(XPS), X-ray diffraction(XRD) and Raman spectroscopy. AES and XPS analysis show that the as-deposited carbon nitride films are mainly composed of [N] and [C], and the composition ratios([N]/[C]) increase as the pulsed laser repetition rate and energy. XRD results show that several diaction peaks attributed toβ-C{sub}3N{sub}4 phase were identified. Raman spectra show that several prominent bands related to C-N bondings could be observed.
