Trouvé à l'intérieur – Page 234Within this definition a number of luminescence forms can be identified which differ only in the way the excited state causing the emission is reached . Luminescence is spontaneous emission of light by a substance not resulting from heat; or "cold light". 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. Frank H. Stephenson, in Calculations for Molecular Biology and Biotechnology (Third Edition), 2016 Abstract.
