Chemiluminescence - Wikipedia
WEBChemiluminescence (also chemoluminescence) is the emission of light ( luminescence) as the result of a chemical reaction, i.e. a chemical reaction results in a flash or glow of light. A standard example of chemiluminescence in the laboratory setting is the luminol test. Here, blood is indicated by luminescence upon contact with iron in hemoglobin.

WEBJan 30, 2023 · The chemiluminescent emitter is a "direct descendent" of the oxidation of luminol (or an isomer like isoluminol) by an oxidant in basic aqueous solution. Probably the most useful oxidant is also hydrogen peroxide similar to peroxyoxalate chemiluminescence; however, other oxidants have been used such as perborate, permanganate (Lu …

WEBchemiluminescence, emission of electromagnetic radiation during the course of chemical reactions. Such radiation, whether ultraviolet, visible, or infrared, is most commonly generated by oxidation. The radiation can usually be ascribed to the transfer of the oxidation energy to a molecule that is itself not undergoing oxidation.

WEBDec 17, 2021 · Chemiluminescence (CL) is the spontaneous emission of light from an electronically excited state of a species produced by a chemical reaction [ 1 ]. Nature uses CL (called bioluminescence) in many living organisms such as fireflies, mushrooms, shells, jellyfish, [ 2] worms and bacteria, mainly for communication or defense roles [ 3 ].

WEBJul 31, 2021 · This behavior is known as chemiluminescence and is transduction of chemical energy (ΔH) ( Δ H) into radiant energy (hν) ( h ν). Chemiluminescence is possible only when the ΔH Δ H of the reaction is sufficiently large to allow for production of at least one of the products in an electronically excited state (∗) ( ∗).
