chemiluminescencen.

Brit.

/ˌkɛmɪˌluːmᵻˈnɛsns/, U.S.

/ˌkɛmiˌluməˈnɛsns/

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: chemical adj., luminescence n.

Etymology: < chemi- (in chemical adj.) + luminescence n., after German Chemiluminescenz (E. Weidemann 1888, in Ann. Physik und Chemie 34 448; now Chemilumineszenz ). Compare earlier chemigraphy n., chemitype n., and also chemio- , variant of chemo- comb. form.

Chemistry.

The emission of light during a chemical reaction, occurring without emission of heat; the light produced by such a reaction.

1889 tr. E. Wiedemann in London, Edinb., & Dublin Philos. Mag. 5th Ser. 28 151 According to the mode of excitation I distinguish Photo-, Electro-, Chemi- [Ger. Chemiluminescenz], and Tribo-luminescence.

1907 Chem. Abstr. 1 267 (title) A Reaction with Green Chemiluminescence.

1942 E. J. Bowen Chem. Aspects of Light xi. 170 The limits separating chemiluminescence from emission due to heat alone, and from electronic excitation..are not as clearly marked as they might be expected to be.

1966 New Scientist 17 Feb. 394/3 Chemiluminescence, which is emitted at room temperature during some chemical reactions.
