Keyword Definition

Also called luminometry.  A low-temperature, analytical procedure related to fluorometry; based on the nature and intensity of the phosphorescent light emitted by an appropriately excited molecule.

Phosphorescence is a specific type of photoluminescence related to fluorescence.  Unlike fluorescence, a phosphorescent material does not immediately re-emit the radiation it absorbs.  The slower time scales of the re-emission are associated with "forbidden" energy state transitions in quantum mechanics. As these transitions occur less often in certain materials, absorbed radiation may be re-emitted at a lower intensity for up to several hours.
