What is CL?
Cathodoluminescence is the emission of photons, as light when a material is stimulated explicitly by high-energy electrons.
Why use CL?
Cathodoluminescence is a unique tool to characterize the optical and electronic properties of materials, while simultaneously correlating them with morphology, microstructure, composition, and chemistry at the micro- and nano-scale.
Modes of operation
The emitted photons may be analyzed by their wavelength (energy), direction, polarization, and lifetime. Advanced detectors have modes of operation to analyze the distribution of one or more of these properties at high spatial resolution.
