Amorphous silicon dioxide nanowire array synthesized via carbonization of polyimide thin film

초록

Amorphous silicon oxide nanowires (SiO(x)NWs) were produced on a large scale by simple heat treatment of the Au nanoparticle/Polyimide/Si thin film stack at 1000 degrees C. The SiO(x)NWs had diameters ranging from 50 to 80 nm with length extending up to 20 mu m. The SiO(x)NWs exhibited intense blue light emission at 420 nm. It was proposed that the formation of the SiO(x)NWs was sustained by the oxygen derived from carbonization of the polyimide thin film, while the Au nanoparticles catalyzed the nanowire growth.
