    a synthetic substance that is fluorescent or phosphorescent; used to coat the screens of cathode ray tubes


  1. Phosphornoun

    A substance capable of exhibiting luminescence. This term is now most commonly used to refer to substances used in fluorescent lights, image intensifiers, or cathode-ray tubes (CRT's), which luminesce when excited by ultraviolet radiation or an electron beam. In color CRT's, three different phosphors, each giving different colors when excited, are used.

  1. phosphor

    A phosphor is a substance that exhibits the phenomenon of luminescence, i.e., it glows in the dark after being charged by exposure to light. It is composed of certain types of chemical elements that, when excited by energy, re-emit absorbed radiation over a longer time. Phosphors are used in many applications such as television screens, computer monitors, radar displays, fluorescent lights, and many more.

  3. Etymology: [Cf. G. phosphor. See Phosphorus.]


  1. Phosphor

    A phosphor, most generally, is a substance that exhibits the phenomenon of luminescence. Somewhat confusingly, this includes both phosphorescent materials, which show a slow decay in brightness, and fluorescent materials, where the emission decay takes place over tens of nanoseconds. Phosphorescent materials are known for their use in radar screens and glow-in-the-dark toys, whereas fluorescent materials are common in CRT and plasma video display screens, sensors, and white LEDs. Phosphors are often transition metal compounds or rare earth compounds of various types. The most common uses of phosphors are in CRT displays and fluorescent lights. CRT phosphors were standardized beginning around World War II and designated by the letter "P" followed by a number. Phosphorus, the chemical element named for its light-emitting behavior, emits light due to chemiluminescence, not phosphorescence, hence it is not a phosphor.
