Luminescence \Lu`mi*nes"cence\, n. [See Luminescent.]
(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.
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.
n. light not due to incandescence; occurs at low temperatures
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 is the third international studio album by Anggun. The French-language version was released in France on 22 February 2005, while English-language version, also with the same title, was first released in Italy on 18 May 2005. The album was later repackaged in August 2006 as Luminescence: Special Edition with three brand new songs. Following her departure from Columbia Records in 2003, Anggun signed a recording contract with Heben Music. The album features production by several musicians, including Jean-Pierre Taïeb, Frédéric Jaffré and Niels Brinck. Anggun co-wrote music and lyrics of the entire album, except two tracks on the French version.
Luminescence became Anggun's comeback album in France, selling over 121,000 copies there. In Indonesia, the album was certified quadruple platinum for exceeding sales of over 450,000 copies as of 2015. With the album, Anggun expanded her popularity to Eastern Europe. Luminescence was certified gold in Russia, while the album's singles accumulatively received more than 79,000 plays on Russian radio according to TopHit.ru. Luminescence received Platinum Export Award for its sales outside France. The album spawned singles " Être une femme", " Cesse la pluie", " Juste avant toi" and "Garde-moi" (featuring David Hallyday) from the French version, as well as "Undress Me", " In Your Mind", " Saviour", " I'll Be Alright" and "A Crime" from the English version.

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.
