Phosphors, are called luminescent materials, or optical transducers, which convert certain types of energy in to electromagnetic radiation over and above thermal radiation. Y2O3 is one such Phosphor. The electromagnetic radiation emitted by a luminescent material is usually in the visible range. The word phosphor means "light bearer" in Greek and it appears in the Greek myths as personification of the morning star Venus .

Produktbeschreibung
Phosphors, are called luminescent materials, or optical transducers, which convert certain types of energy in to electromagnetic radiation over and above thermal radiation. Y2O3 is one such Phosphor. The electromagnetic radiation emitted by a luminescent material is usually in the visible range. The word phosphor means "light bearer" in Greek and it appears in the Greek myths as personification of the morning star Venus . A phosphor is any substance capable of absorbing energy and re-emitting it in the form of visible light. the phosphorescence, which means persisting light emission from a substance after the exciting radiation has ceased, was derived from the word phosphor. The word fluorescence refers to the light emission from a substance during the time when it is exposed to exciting radiation.
