摘要
In this paper, we report preliminary studies on luminescence emission from bundles of multiwalled carbon nanotube (MWCNT) induced either by heating (thermo-luminescence, TL) or by ion bombardment of (iono-luminescence, IL) the sample. For N-2 exposure we do not observe any evidence of N-2 absorption on the sample. For 2 keV N-2(+) ion bombardment or Na vapour deposition or Na+ ion implantation, IL spectra show a continuous decrease of luminescence intensity. These results are interpreted as due to an increasing sample doping. (C) 2006 Elsevier Ltd. All rights reserved.
