Photonics Dictionary

phosphor: A chemical substance that exhibits fluorescence when excited by ultraviolet radiation, x-rays or an electron beam. The amount of visible light is proportional to the amount of excitation energy. If the fluorescence decays slowly after the exciting source is removed, the substance is said to be phosphorescent.
