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 N2 exposure we do not observe any evidence of N2 absorption on the sample. For 2 keV Nþ 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.

Abstract
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 N2 exposure we do not observe any evidence of N2 absorption on the sample. For 2 keV Nþ 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.File in questo prodotto:
