Phosphorescent

Phosphorescent describes the property of emitting light after exposure to a source of radiant energy, such as ultraviolet light or X-rays. Unlike fluorescence, phosphorescence continues to emit light for a period of time after the energy source is removed. This delayed luminescence is caused by the gradual release of absorbed energy, making phosphorescent materials glow in the dark. The duration and intensity of the glow varies depending on the material's chemical composition.
