Abstract :
Needle-shaped 3C–SiC nanowires were grown from commercially available SiC powders in a thermal evaporation process with iron as catalyst. A strong broad photoluminescence peak located around 450 nm was observed at room temperature, which may be ascribed to quantum size effects of nanomaterials. Needle-shaped 3C–SiC nanowires may have great potential applications such as blue-green light-emitting diodes and display devices.
