Abstract: Ultralong nanosilicon carbide rods were prepared by modified PECVD (plasma enhanced chemical vapor deposition) technique,which is four hexagonal multi-type structure.Their diameters range from 18 to 50nm with high resolution TEM,and their lengths range from 0.3μm to 6mm. Raman spectra show that it is 4 hexagonal poly-type nano-silicon carbide rod,and the exciton of ultraviolet emerges strongly in deep region,meanwhile two wide emitting bands emerge at 550~620nm and 700~750nm,respectively.The computing illustrates that the SiC bandwidth is 3.98eV,and this phenomena is not fitted into the computing results according to quantum mechanism.
