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.

WebDec 17, 2021 · Introduction. 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 …

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.

WebMay 25, 2011 · Chemiluminescence is the production of light from a chemical reaction. Two chemicals react to form an excited (high-energy) intermediate, which breaks down releasing some of its energy as photons of light (see glossary for all terms in bold) to reach its ground state (see Figure 1 , below).

WebNov 15, 2019 · In chemiluminescence (CL), the energy is provided by the homogeneous chemical reaction (s) between at least two reagents, i.e. chemi-excitation. ECL is a specific case where these reactive species are produced electrochemically at the electrode surface, i.e. electro-chemi-excitation.

WebChemiluminescence (CL) is an emission phenomenon induced by chemical reaction. Different from the photoluminescence, CL is free from external excitation source, which is expected to show great advantages such as higher signal-to-background ratio (SBR) in bioimaging, and deeper tissue penetration in photodynamic therapy (PDT).

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 (∗) ( ∗).
