The emission of light during a chemical reaction that does not produce significant quantities of heat
Web Definitions:
- luminescence resulting from a chemical reaction as the oxidation of luciferin in fireflies
- The emission of light as the result of a chemical reaction
- is light emitted during (cold) chemical reactions.
- an exoergic chemical reaction that produces a product molecule in an electronically excited state that relaxes via fluorescence or phosphorescence. The intensity of light produced is proportional to the rate of production of the excited state molecule. ...
- luminescence produced by chemical processes
- is when the light emitted after the energy being absorbed is from a chemical reaction not in a living organism. We all love glow sticks, which illustrates this process perfectly. When a glow stick is bent, a glass vile inside releases the chemicals and produce light.
- a trace detection technique in which explosives are detected via light that is emitted from NO molecules in a chemically excited state. The excited state NO molecules are formed through deliberately induced decomposition of the nitro (NO2) groups in the original explosive compound.
- light emission from a chemical reaction, not ascribable to incandescence (q.v.). This phenomenon produces little or no heat and is commonly called "cold light."
