WebEach phosphor consists of a host material mixed with a lanthanide chromaphore or activator (making up 2-5 percent of the total). Intematix offers aluminates, garnets, nitrides, and silicates in green, yellow, red, and … WebActivator (phosphor) In phosphors and scintillators, the activator is the element added as dopant to the crystal of the material to create desired type of nonhomogeneities. In luminescence, only a small fraction of atoms, called emission centers or luminescence centers, emit light. In inorganic phosphors, these inhomogeneities in the crystal ...
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 … See more The scintillation process in inorganic materials is due to the electronic band structure found in the crystals. An incoming particle can excite an electron from the valence band to either the conduction band or the See more Many phosphors tend to lose efficiency gradually by several mechanisms. The activators can undergo change of valence (usually oxidation), the crystal lattice degrades, atoms – … See more Various Some other phosphors commercially available, for use as X-ray screens, neutron detectors, alpha particle scintillators, etc., are: See more • Cathodoluminescence • Laser • Luminophore See more Phosphors are usually made from a suitable host material with an added activator.
