| phosphorescence | 1. <chemistry> Emission of light following absorption of radiation. Emitted light is of longer wavelength than the exciting radiation and is a result of decay of electrons from the triplet to the ground state. Lasts longer than fluorescence electron decay from singlet to ground state) and occurs after a longer delay. 2. <biology> Popularly misused as a term for biological luminescence, for example by fireflies.

| phosphorescence |
Phosphorescence is the result of a radiative (light emitting) transition involving a change in the spin multiplicity of (in most cases) a molecule from excited state singlet to excited state triplet. This transition is quantum mechanically forbidden as is the transition that leads to light emission. ...

| phosphorescence |
Emission of visible light by a substance, such as a mineral, that is exposed to ultraviolet light and absorbs radiation from it. The light appears in the form of glowing, distinctive colors. The emission continues after the exposure to ultraviolet light ends.

| phosphorescence |
Luminescence that persists after a light source has been removed. Materials such as phosphors or phosphorogens are activated from a light source to emit the light in the form of photons of light.
