A phosphor is a substance that exhibits the phenomenon of luminescence; it emits light when exposed to some type of radiant energy. The term is used both for fluorescent or phosphorescent substances which glow on exposure to ultraviolet or visible light, and cathodoluminescent substances which glow when struck by an electron beam (cathode rays) in a cathode-ray tube. WebSep 24, 2024 · Substituting a phosphorus atom (with five valence electrons) for a silicon atom in a silicon crystal leaves an extra, unbonded electron that is relatively free to move around the crystal. The most common method of doping is to coat the top of a layer of silicon with phosphorus and then heat the surface. This allows the phosphorus atoms to ... WebSep 8, 2024 · Element Symbol: P.
