| Outline of Final Research Achievements |
Graphitic carbon nitride films were prepared based on chemical vapor deposition. It was confirmed by X-ray diffraction that C-N sheets of the film are well stacked parallel to the substrate. The (hk0) XRD pattern well corresponded to simulated one of polymer carbon nitride sheets. The optical absorption coefficient was shown by optical transmittance and reflectance spectra, and also photothermal deflection spectroscopy. The optical bandgap was estimated to be 2.9 eV from a Tauc plot, where it is larger than powder samples. We measured a photocurrent spectrum. The photocurrent was proportional to the optical absorption. The photosensitivity was 1.5×10e3 at 340 nm (2mW/cm2).
