Chemiluminescence (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.
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.
Peroxyoxalate chemiluminescence (CL) was first reported by Rauhut in 1967 [1] in the reaction of diphenyl oxalate. The emission is generated by the reaction of an oxalate ester with hydrogen peroxide in the presence of a suitably fluorescent energy acceptor. This reaction is used in glow sticks. Glow sticks using peroxyoxalate CL
This is a list of sources of light, the visible part of the electromagnetic spectrum.Light sources produce photons from another energy source, such as heat, chemical reactions, or conversion of mass or a different frequency of electromagnetic energy, and include light bulbs and stars like the Sun. Reflectors (such as the moon, cat's eyes, and mirrors) do not actually produce the light that ...
When the outer container is flexed, the inner container breaks, allowing the solutions to combine, causing the necessary chemical reaction. After breaking, the tube is shaken to thoroughly mix the components. The glow stick contains two chemicals, a base catalyst, and a suitable dye (sensitizer, or fluorophor). This creates an exergonic reaction.
The particles eminating from burning scented wax melts indoors can create a “tremendous amount” of indoor air pollution — similar to pollution caused by diesel engines.
Luminol (C 8 H 7 N 3 O 2) is a chemical that exhibits chemiluminescence, with a blue glow, when mixed with an appropriate oxidizing agent.Luminol is a white-to-pale-yellow crystalline solid that is soluble in most polar organic solvents but insoluble in water.
Eosinophilic esophagitis, an immune system reaction to certain foods, allergens or environmental factors, can cause damage to the esophageal lining, leading to swelling, scarring and narrowing of ...
