Phosphorescence refers to a pigment that converts wavelengths outside the visible spectrum—such as UV light—into visible light, resulting in brilliant hues and glowing effects. Phosphoresce materials do not immediately re-emit the light they absorb, meaning that when phosphorescence pigments are no longer exposed to this stimulant, they will continue to glow at an ever-decaying rate. This is the main difference between fluorescent and phosphorescent, as fluorescent pigments stop admitting light as soon and they are no longer exposed to their source of stimulus.

 While these pigments are most effectively suspended in media such as paints, inks and glazes, or polymers, they can then be applied to a wide array of substrates.
