本文报道了用偏压辅助热丝化学气相沉积法制备的硼碳氮（BCN）纳米管的拉曼光谱。观察到BCN纳米管的拉曼光谱达到四阶。与纯碳纳米管相比，BCN纳米管的拉曼谱带展宽，D模相对于G模的相对强度随B和N原子浓度的增加而变化。高分辨透射电子显微镜获得的微观结构的基础上，已研究了潜在的机制。(C)2002年美国物理学会。
A systematic Raman study of boron carbonitride (BCN) nanotubes, synthesized by bias-assisted hot filament chemical vapor deposition, is reported. Raman spectra up to the fourth order are observed from the BCN nanotubes. Comparing with pure carbon nanotubes, the Raman bands in BCN nanotubes are broadened and the relative intensity of the D mode with respect to the G mode varies with increasing B and N atomic concentrations. The underlying mechanism has been studied on the basis of the microstructures obtained by high-resolution transmission electron microscopy. (C) 2002 American Institute of Physics.
