Abstract
AbstractIn this work we analysed, by means of Spectral Imaging Cathodoluminescence, the luminescence properties of individual ZnO nanowires (NWs) grown by chemical vapour deposition. The NWs show a general increase of the radiative recombination channels, and a decrease of the relative intensity of the visible band respect to the bound exciton emission, pointing to a high crystal quality. Local changes in the peak position and intensity of the near band edge were found by studying the luminescence of individual NWs, which have been ascribed to structural changes along them (© 2012 WILEY‐VCH Verlag GmbH & Co.
