Description
Phosphor (from armor. lumen — light, etc. - Greek  — bearing) — the substance capable to transform the energy absorbed by it to light radiation (to luminesce).
By the chemical nature phosphors are divided on inorganic, the majority of which belongs to crystalline phosphors, and organic. The luminescence of inorganic phosphors (crystalline phosphors) is caused in most cases by presence of the foreign cations which are contained in small quantities (from 2% to 0,0001%). Such impurity (activators) usually are ions of metals; for example, the luminescence of sulfide of zinc is activated by a copper ion. Inorganic phosphors apply in luminescent lamps, electron beam tubes, to production of x-ray screens, serve as radiation indicators, etc. Organic phosphors (lyumogen) apply to production of bright fluorescent paints, the luminescing materials, use in the sensitive luminescent analysis in chemistry, biology, medicine and criminalistics.
