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. Here, blood is indicated by luminescence upon contact with iron in hemoglobin.

2025年1月21日 · Chemiluminescence is the emission of light as a result of a chemical reaction. Unlike incandescence, which requires high temperatures to produce light, chemiluminescence occurs at relatively low temperatures, making it a “cold light.” Chemiluminescence: Key Points. Chemiluminescence is the emission of light from a chemical reaction.

2019年8月16日 · Chemiluminescence is defined as light emitted as the result of a chemical reaction. It's also known, less commonly, as chemoluminescence. Light isn't necessarily the only form of energy released by a chemiluminescent reaction. Heat may also be produced, making the reaction exothermic.

When it results from an electronically excited state of a species produced by a chemical reaction, it is called chemiluminescence (CL). The phenomenon can take place both in natural and artificial chemical systems and it has been utilized in a variety of applications.

Chemiluminescence, 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

2023年1月30日 · Most chemiluminescence methods involve only a few chemical components to actually generate light. Luminol chemiluminescence (Nieman, 1989), which has been extensively investigated, and peroxyoxalate chemiluminescence (Given and Schowen, 1989; Orosz et al., 1996) are both used in bioanalytical methods and will be the subject of this primer on ...

2011年5月25日 · 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).

Chemiluminescence (CL) is the term used to describe the phenomena in which a substance can absorb chemical energy during a chemical reaction to change into an excited state before returning to its ground state when exposed to light. You might find these chapters and articles relevant to this topic.

Chemiluminescence Definition. We define chemiluminescence as the light emission as a result of the chemical reaction. During the product formation, light isn't necessarily the only form of energy released by a chemiluminescent reaction. Besides, heat may also release, making the reaction exothermic. How Chemiluminescence Works?

1999年4月19日 · Chemiluminescence occurs when luciferase in this insect's lower abdomen reacts with oxygen to produce the flashes of light seen during courtship. To explain this phenomenon, we...
