New hexagonal-shaped SiC nanowires were synthesized through a sol–gel and direct heating process. Electron microscopy, X-ray diffraction and Raman spectrum indicate the nanowires possess a β-SiC structure and have typical diameters of 50–100nm and length up to several tens of micrometers. Two strong broad ultraviolet light emission peaks at about 290 and 396nm are observed at room temperature from...
