Cathodoluminescence imaging is an appealing technique due to its ease of use, reproducibility, speed, and high spatial resolution. The well-defined electron probe and the large choice of detection modalities enable a myriad of applications.
Cathodoluminescence emission can be used to explore many fundamental properties of matter. It can be used to study light transport, scattering, electronic structure of a material, resonant phenomena and much more. It thus presents a valuable source of information for fundamental research as well as applied research with a direct link to industry.
