Description

A substance that exhibits luminescence. A phosphor can absorb energy at one wavelength (such as from x-rays, UV radiation or alpha particles) and emit the energy at a different wavelength (in the UV, visible or infrared). A substance that ceases emission when the source stops is called fluorescent. Materials that continue to emit light for a period after the removal of the exciting energy are called phosphorescent or phosphors. Phosphors are used in fluorescent light tubes, televisions cathode ray tubes and instrument dials. Some phosphors used in fluorescent lamps are: calcium tungstate, magnesium tungstate, zinc silicate, calcium silicate, cadmium borate, magnesium arsenate.
