Abstract:

Large-scale highly aligned boron carbonitride (BCN) nanofibers with controllable orientations and chemical compositions were synthesized directly on nickel substrates from a gas mixture of N₂, H₂, CH₄, and B₂H₆ by plasma-enhanced hot filament chemical vapor deposition.The morphology of the BCN nanofibers was examined by scanning electron microscopy, the microstructures were studied by high-resolution transmission electron microscopy, and the bonding states as well as chemical compositions were determined by electron energy loss spectroscopy. To our knowledge, this is the first report on the photoluminescent properties of BCN nanofibers that shows that they are interesting blue- and violet-light-emitting materials with tunable wavelengths. Further studies on field electron emission suggest that BCN nanofibers are also promising candidates for field emission sources.
