chemiluminescence
Noun: - Light emission from a chemical reaction: Chemiluminescence is the emission of light (luminescence) as a direct result of a chemical reaction, without the significant production of heat. This is the phenomenon seen in fireflies and some laboratory tests.
Chemiluminescence is a scientific term used primarily in chemistry, biology, and related fields to describe a specific type of light-producing reaction. - It occurs when a chemical reaction produces an excited intermediate or product that then releases energy in the form of visible light as it returns to a lower energy state. - The light from a firefly is a classic, natural example of chemiluminescence.
- The chemiluminescence of a firefly's tail is a beautiful example of bioluminescence, which is a form of chemiluminescence in living organisms.
- Forensic investigators sometimes use a reagent that produces chemiluminescence to detect traces of blood at a crime scene.
- The laboratory demonstration showed a bright blue chemiluminescence when the two chemicals were mixed.
- Analytical Chemistry: Chemiluminescence is employed in sensitive analytical techniques to detect and quantify specific substances, such as in immunoassays or for monitoring air pollutants like nitrogen oxides.
- Bioluminescence: This is a subset of chemiluminescence where the light-producing chemical reaction occurs within a living organism (e.g., fireflies, jellyfish, certain fungi).
- Chemiluminescent (adjective): Describing something that exhibits or relates to chemiluminescence.
- The chemiluminescent reaction glowed in the dark flask.
- Bioluminescence (noun): Chemiluminescence produced by biological systems within living organisms.
- Cold light: A general term for light emitted without high heat, which includes chemiluminescence, bioluminescence, and phosphorescence. (Note: This is a broader, less precise synonym.)
(This is a technical/scientific term, so it does not have common idiomatic or phrasal verb uses in everyday language.)
-
luminescence resulting from a chemical reaction as the oxidation of luciferin in fireflies
