%X Ultrafine powders containing alumina nanowires are synthesized by DC arc plasma from pure aluminium metal.Nanowires grow only when reactive gases are composed of nitrogen and less than ten percent of oxygen.Nanowires have the diameters ranging from 20 to 80 nm and lengths ranging from hundreds nanometers to tens of micrometers. A first assumption of the mechanism process is proposed, in which nanowires grow starting directly from the aluminium. Photoluminescence measurements show that the powders have three emission peaks around 435,530 and 750 nm resulting from different kinds of defects such as oxygen vacancies,aluminium interstitial ions and surface defects.
