Chemiluminescence differs from fluorescence or phosphorescence in that the electronic excited state is the product of a chemical reaction rather than of the absorption of a photon. It is the antithesis of a photochemical reaction, in which light is used to drive an endothermic chemical reaction.
Electrochemiluminescence or electrogenerated chemiluminescence (ECL) is a kind of luminescence produced during electrochemical reactions in solutions. In electrogenerated chemiluminescence, electrochemically generated intermediates undergo a highly exergonic reaction to produce an electronically excited state that then emits light upon relaxation to a lower-level state.
Chemiluminescence is the emission of light through a chemical reaction.It contrasts with fluorescence, which is excited by a light source.During chemiluminescence, the vibrationally excited product of an exoergic chemical reaction relaxes to its ground state with the emission of photons. [1]
Diphenyl oxalate (trademark name Cyalume) is a solid whose oxidation products are responsible for the chemiluminescence in a glowstick. This chemical is the double ester of phenol with oxalic acid. Upon reaction with hydrogen peroxide, 1,2-dioxetanedione is formed, along with release of the two phenols. [2]
Luminol and haemoglobin, an example of chemiluminescence UV-photoluminescence in microbiological diagnostics. Luminescence is a spontaneous emission of radiation from an electronically or vibrationally excited species not in thermal equilibrium with its environment.
Lophine is the organic compound with the formula (C 6 H 5 C) 2 N 2 HCC 6 H 5.It is a derivative of imidazole wherein all three carbon atoms have phenyl groups as substituents.A white solid, this compound gave the first example of chemiluminescence when its basic solutions were exposed to air. [1]
Chemiluminescence, the type of light used in glow sticks, is a "cold-light" and does not use electricity, and will not cause a gas leak to ignite. Glow sticks are also used worldwide in the marine industry, often used as fishing lures in long-line, recreational, and commercial fishing, as well as for personnel safety.
Luminescence: The Journal of Biological and Chemical Luminescence is a monthly peer-reviewed scientific journal publishing original scientific papers, short communications, technical notes, and reviews on fundamental and applied aspects of all forms of luminescence, including bioluminescence, chemiluminescence, electrochemiluminescence, sonoluminescence, triboluminescence, fluorescence, time ...
