phosphorescence

phosphorescence

 [fos″fo-res´ens]
the emission of light without appreciable heat; it is characterized by the emission of absorbed light after a delay and at a considerably longer wavelength than that of the absorbed light. adj., adj phosphores´cent.

phos·pho·res·cence

(fos'fŏ-res'ĕnts),
The quality or property of emitting light without active combustion or the production of heat, generally as the result of prior exposure to radiation, which persists after the inciting cause is removed.
[G. phōs, light, + phoros, bearing]

phosphorescence

(fŏs′fə-rĕs′əns)
n.
1. Persistent emission of light following exposure to and removal of incident radiation.
2. Emission of light without appreciable heat, as from chemiluminescence of phosphorus or bioluminescence of living organisms.

phos′pho·res′cent adj.
phos′pho·res′cent·ly adv.

phos·pho·res·cence

(fosfŏr-esĕns)
The quality or property of emitting light with neither active combustion nor production of heat, generally as the result of prior exposure to radiation, which persists after the inciting cause is removed.
[G. phōs, light, + phoros, bearing]

phosphorescence 

Luminescence that persists for some time after the exciting stimulus has ceased.

Biacetyl has been demonstrated to be an elegant molecular tracer for flow measurements mainly due to its longer phosphorescence lifetime which allows measuring both high and low speed flows.
The phosphorescence increased in intensity through July and into August (Williamson 1901).
We must also factor in glow or phosphorescence, which like fluorescence is a form of luminescence.
Swimming over pink and green coral, you see shoals of fish and at night, under a full moon, the water is filled with phosphorescence which glows as you move around.
"Valuable papers, like passports and money, are usually made of cotton and cellulose, an ideal medium for visualizing phosphorescence at room temperature," said Ghauch, who claimed his system can distinguish counterfeit notes in five milliseconds.
After dark, we discovered an additional and unexpected source of light in the form of phosphorescence. A glowing ball of bioluminescent organisms would swirl along the length of the kayak each time I planted my paddle in the water, providing Ian (who sat in the stern of my kayak) with a spectacular light show.
