Conversion of vertically-aligned boron nitride nanowalls to photoluminescent CN compound nanorods: Efficient composition and morphology control via plasma technique

摘要: Abstract Two-dimensional BN/CN nanomaterials of various composition and morphology were synthesized in N2 H2 plasma by plasma-enhanced hot filament chemical vapor deposition, with B4C used as precursor. The results field emission scanning electron microscopy, X-ray diffractometer, transmission micro-Raman photoelectron spectroscopy evidence that the hexagonal boron nitride nanowalls carbon oxide phases under about 1:1 ratio to N2, while CN nanorods are formed other ratios nanowires made grown without plasma. Efficient control over nanostructure was demonstrated, thus proposing a cheap convenient fabrication technique for advanced composite nitride/graphene materials. photoluminescence properties BN also studied using 325 nm line He Cd laser excitation source. fabricated can generate ultraviolet, blue green multi-PL bands, which associated defects these clusters, respectively. These outcomes make great contribution design functional BN- CN-nanomaterials morphologies compositions applications electronic carbon-based optoelectronic nanodevices.
