Cathodoluminescence imaging and spectroscopy on a single multiwall boron nitride nanotube

Cathodoluminescence imaging and spectroscopy experiments on a single bamboo-like boron nitride nanotube are reported. Imaging experiments show that the luminescence is located all along the nanotube. Spectroscopy experiments point out the important role of dimensionality in this one dimensional object. (c) 2007 Elsevier B.V. All rights reserved.
