Luminescence Luminescence is emission of light by a substance not resulting from heat; it is thus a form of cold body radiation Source: http://en.wikipedia.org/wiki/Luminescence (accessed June 22nd 2012)

Bioluminescence - Lifesaver?
Firefly bioluminescence: Emission oxidation of luciferin Proteins and substrates - mostly unrelated Most referred to as luciferin / luciferase.
