摘要: Carbon nitride films have been synthesized by argon ion-beam sputtering from a biomolecular compound target, 8-aza-6-aminopurine (C4N6H4) The compound has a six-membered ring structure similar to that existing in the hypothetical beta-C3N4. Except fur the target material, no other source of nitrogen was used during sputtering deposition. It was found that crystalline carbon nitride with high N/C atomic composition ratios of 0.43-0.56 can be formed even at room temperature. The infrared spectra of the film exhibit two peaks at 1383 and 1643 cm(-1), corresponding to C-N and C=N stretching modes, respectively. No detectable peak at 2200 cm(-1) (C=N stretching mode) is observed. Both x-ray diffraction and transmission electron microscopy show a very strong broad peak at 3.2 Angstrom, comparable to the d spacing of the (110) orientation in the beta-C3N4 structure. However, it is suggested that the film contains a nanocrystalline phase with a crystal structure yet to be determined. (C) 1998 American Institute of Physics.
