【Abstract】 Al 3O 3N nanowires were successfully synthesized by dc arc-discharge in H 2+Ar with a little amount of N 2+O 2. Composition,morphologies,microstructures were characterized using x-ray diffraction,scanning electron microscopy,Transmission electron microscopy(TEM),and high resolution TEM. The synthesized Al 3O 3N nanowires had the diameters ranging from 25 to 110 nm and the lengths up to 5.5 μm. Al 3O 3N nanowires is of a spinel type structure. Besides,the growth mechanism of Al 3O 3N has also been studied.更多还原
