The main purpose of X-Ray phosphors is to respond to X-Rays which re-emit energy as visible photons. They can be incorporated into a wide variety of X-Ray imaging devices, including within medical and security applications.

Phosphors are designated by the letter P followed by a number. Phosphors are often rare-earth compounds with an activator. The activators in phosphor prolong the emission time (afterglow) or sometimes can be used to quench and shorten its afterglow.

Electron backscatter diffraction (EBSD) is a technique used in the scanning electron microscope (SEM) to collect and explore quantitive microstructure analysis data such as, crystal orientation, phase grain statistics, phase and strain conditions and defects
