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.

  2. (Zo["o]l.)

    1. The faculty or power of producing light by biological processes, as in the firefly and glowworm. Also called bioluminescence.

    2. The light produced by biological or biochemical processes. Also called bioluminescence.

Douglas Harper's Etymology Dictionary

1884, from Latin lumen (genitive luminis) "light" (see luminous) + -escence.\n\nFluorescence and Phosphorescence -- Prof. E. Wiedmann has made a new study of these phenomena. He proposes the general name luminescence for evolutions of light which do not depend on the temperature of the substance concerned.

["Photographic News," April 20, 1888]


n. (context physics English) Any emission of light that cannot be attributed merely to the temperature of the emitting body.

  1. n. light not due to incandescence; occurs at low temperatures

  2. light from nonthermal sources [syn: glow]


Luminescence is emission of light by a substance not resulting from heat; it is thus a form of cold-body radiation. It can be caused by chemical reactions, electrical energy, subatomic motions, or stress on a crystal. This distinguishes luminescence from incandescence, which is light emitted by a substance as a result of heating. Historically, radioactivity was thought of as a form of "radio-luminescence", although it is today considered to be separate since it involves more than electromagnetic radiation. The term 'luminescence' was introduced in 1888 by Eilhard Wiedemann. The dials, hands, scales, and signs of aviation and navigational instruments and markings are often coated with luminescent materials in a process known as "luminising".

Luminescence (journal)

Luminescence: The Journal of Biological and Chemical Luminescence is a bimonthly peer-reviewed scientific journal publishing original scientific papers, short communications, technical notes, and reviews on fundamental and applied aspects of all forms of luminescence, including bioluminescence, chemiluminescence, electrochemiluminescence, sonoluminescence, triboluminescence, fluorescence, time-resolved fluorescence, and phosphorescence. The current editor-in-chief is L.J. Kricka ( University of Pennsylvania). It was established in 1986 by John Wiley & Sons as the Journal of Bioluminescence and Chemiluminescence and obtained its current title in 1999.
