Chemical compounds that emit light when struck by a beam of electrons. The amount of light emitted is proportional to the intensity of the electron beam. RGB monitors use three different phosphors to produce red, green, and blue light.
Chemical powders used to coat fluorescent tubes. They become excited when subjected to the ultraviolet light produced by the discharge in a luminous tube. A range of phosphors is available and is capable of producing a large variety of colors and whites.
Materials that emit light when irradiated by cathode rays, or when placed in an electric field. The quantity of visible light is proportional to the amount of excitation energy present.
The white, powdered material coating the inside of the glass tube of a lamp. The phosphors fluoresce (emit visible light) when excited by the ultraviolet radiation produced by the mercury vapor that is energized by the electric arc sustained inside the lamp.
These are materials that illuminate when struck by electrons. They produce the images on monitor screens. There are three different phosphors used, Red, Green, and Blue.
Collided by the electrons emitted by the filament, the phosphor is excited and emits light.
Chemical compounds that are used to coat the inside of fluorescent and some HID lamps.
Red, green and blue chemical surfaces behind the screen that illuminate when struck by beams from the electron gun. The actual sources of colour and images onscreen.
Tiny red, green, and blue grains on the inside surface of a CRT monitor that are illuminated when an electron beam is directed toward them.
