Fluorescence vs. Phosphorescence

Fluorescencenoun

(physics) The emission of light (or other electromagnetic radiation) by a material when stimulated by the absorption of radiation or of a subatomic particle.

Fluorescencenoun

The light so emitted.

Fluorescencenoun

A luminescence emitted by certain substances due to the absorption of radiation at one wavelength, and the almost instantaneous re-emission of radiation at another, usually longer wavelength. The re-radiation stops almost as soon as the incident radiation is halted, thus distinguishing this phenomenon from phosphorescence, in which re-radiation of light may continue for some time after the incident radiation is halted.

Fluorescencenoun

light emitted during absorption of radiation of some other (invisible) wavelength

Fluorescence

Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence.

Phosphorescencenoun

The emission of light without any perceptible heat; the quality of being phosphorescent.

Phosphorescencenoun

The quality or state of being phosphorescent; or the act of phosphorescing.

Phosphorescencenoun

A phosphoric light.

Phosphorescencenoun

a fluorescence that persists after the bombarding radiation has ceased

Phosphorescence

Phosphorescence is a type of photoluminescence related to fluorescence. When exposed to light (radiation) of a shorter wavelength, a phosphorescent substance will glow, absorbing the light and reemitting it at a longer wavelength.
