Outline
Carbon nitride comprises super physical and chemical properties and abroad applications. Its structure and character were reviewed, and the synthetic methods, including CVD, ion beam sputtering, laser ablation, ion plating and ion irradiation et al., were completely introduced. The perspectives of the investigations of the super-hard carbon nitride were discussed by looking at the new progresses achieved in the corresponding application studies. The experimental results show that crystallites of a little cubic C-N compound dispersed in an amorphous matrix. FTIR spectroscopy showed that the films contain mainly C=C and sp2/sp3 C-C bonds. X-ray diffraction and SEM studies indicate that the deposited films may consist of the nano-sized β-C3N4. Crystallites embedded in matrix of graphite form of C3N4 structure, and the crystalline phases are high enough to be detected by XRD.
