用氮离子束分别原位溅射 Ti和石墨靶的方法制备了 CNx/TiNy多层膜用 X射线光电子谱分析 CNx层中 C和N的键合状态,用透射电镜观察薄膜中的相形貌,用电子衍射和 X射线衍射的方法分析相的结构.结果表明, CNx层中主要有 N—sp2C和 N—sp3C两种键合状态,薄膜中观察到的 C-N化合物尺寸为 10-60nm的晶体颗粒,其衍射数据可用立方C3N4结构标定.证实了该薄膜中存在立方 C3N4化合物
CNx / TiNy multilayers were prepared by in-situ sputtering of Ti and graphite target with nitrogen ion beam respectively. The bonding state of C and N in CNx layer was analyzed by X-ray photoelectron spectroscopy. The phase morphology was observed by transmission electron microscope , The structure of the phase was analyzed by electron diffraction and X-ray diffraction. The results show that there are mainly two kinds of bonding states of N-sp2C and N-sp3C in the CNx layer. The crystal particles with C-N compound size of 10-60nm are observed in the film. The diffraction data can be calibrated with cubic C3N4 structure. It was confirmed that cubic C3N4 compounds were present in the film
