© 2015 Elsevier Ltd. All rights reserved. Cathodoluminescence (CL) is an enabling quantitative technique for the characterisation of luminescent materials. In this chapter, following a brief review of the basic principles and recent advances in CL imaging and spectroscopy, a number of examples are chosen to demonstrate the utility of CL for the microcharacterisation of semiconductor nanowires, with a focus on ZnO material. Various analytical methods such as monochromatic CL imaging, depth-resolved analysis, and excitation density-resolved analysis are presented, which can provide information on the local optical and electronic properties of nanowires at the nanometre spatial resolution.
