Luminescence \Lu`mi*nes"cence\, n. [See {Luminescent}.]
1. (Physics) Any emission of light not ascribable directly to
incandescence, and therefore occurring at low
temperatures, as in phosphorescence and fluorescence or
other luminous radiation resulting from vital processes,
chemical action, friction, solution, or the influence of
light or of ultraviolet or cathode rays, etc.
[Webster 1913 Suppl.]

2. (Zool.)
(a) The faculty or power of producing light by biological
processes, as in the firefly and glowworm. Also called
{bioluminescence}.

processes. Also called {bioluminescence}.
