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}.
      (b) The light produced by biological or biochemical
          processes. Also called {bioluminescence}.
