Chemiluminescence - Wikipedia
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.

Direct and Indirect Chemiluminescence: Reactions, Mechanisms …
Emission of light by matter can occur through a variety of mechanisms. 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 - an overview | ScienceDirect Topics
Chemiluminescence is luminescence caused by a chemical reaction, usually a redox reaction, in which some molecule in the reaction system gains energy from the reaction to be excited and emits light to return the ground state. Chemiluminescence can be categorized into direct chemiluminescence and indirect chemiluminescence [26].
What is chemiluminescence? - Science in School
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, 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 …
Chemiluminescence - Definition, Working, Examples and Factors …
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?
Chemiluminescence - an overview | ScienceDirect Topics
Chemiluminescence is the conversion of chemical energy into the emission of visible light (luminescence) as the result of an oxidation or hydrolysis reaction. This technology provides a very sensitive, cost-effective detection alternative to many radioisotopic and fluorescence techniques, and most chromogenic detection processes ( Table 14.2 ).
