Understanding Cathodoluminescence and Cathodofluorescence in Materials Science

Cathodoluminescence (CL) is a form of luminescence that occurs when a material is bombarded with high-energy particles, such as electrons or ions. This process can cause the material to emit light, often in the form of a glow or a fluorescent color. Cathodoluminescence is commonly used in materials science and electron microscopy to study the properties of materials at the nanoscale.

Cathodofluorescence (CF) is a specific type of cathodoluminescence that occurs when a material is exposed to a high-energy electron beam and emits light as a result. This process is similar to photoluminescence, but instead of being excited by photons, the material is excited by the electrons in the electron beam. Cathodofluorescence is often used to study the properties of materials in electron microscopes, as it can provide detailed information about the material's optical and electronic properties.

In summary, cathodoluminescence is a general term that refers to the emission of light by a material that has been bombarded with high-energy particles, while cathodofluorescence is a specific type of cathodoluminescence that occurs when a material is exposed to an electron beam and emits light as a result.
