What is cathodoluminiscence?
Cathodoluminescence (CL) is the emission of light from a material when it is excited by incident electrons. CL microscopy utilizes this phenomenon to analyze and characterize various materials at the nanoscale. It has been used for the characterization of color centers, excitons, plasmonic and nanophotonic systems, as well as semiconductors, minerals, ceramics, and nanostructured materials . CL measurements can be performed in scanning transmission electron microscopes (STEM) and scanning electron microscopes (SEM) . CL microscopy offers advantages such as ultrahigh spatial resolution, the ability to analyze spatial, spectral, and temporal properties, and the correlation with other analytical techniques available in the electron microscope . It has been used for a wide range of applications, including imaging, spectroscopic detection, and opto-electronic investigations at the nanoscale . The technique has seen significant advancements in recent years, expanding its capabilities and potential for future research .
