Chemiluminescence is a result of a chemical reaction. In fact, bioluminescence is a type of chemiluminescence. For example, the catalyzed reaction between luminal and hydrogen peroxide produces light. Electrochemiluminescence is a type of luminescence produced during an electrochemical reaction.n fact, bioluminescence is a type of chemiluminescence.

The attractiveness of chemiluminescence as an analytical tool is the simplicity of detection. The fact that a chemiluminescent process is, by definition, its own light source means that assay methods and the instruments used to perform them need only provide a way to detect light and record the result.Luminometers need consist of only a light-tight sample housing and some type of photodetector.he fact that a chemiluminescent process is, by definition, its own light source means that assay methods and the instruments used to perform them need only provide a way to detect light and record the result.
