Abstract

A large quantity of nanowires and nanotubes of silicon oxide are produced by using Fe–Co–Ni alloy nanoparticles as catalyst. The products have a uniform diameter of around 100 nm. The nanowires have a smooth surface and the lengths are up to 100 μm or more. A new morphology called a serrated joint nanotube was found. The alloy catalyst plays a key role in the synthesis process. Room-temperature photoluminescence measurement under excitation at 360 nm showed that the silicon oxide had a strong blue-green emission at 525 nm (about 2.36 eV), which may be related to oxygen defects.
