The luminol reaction is an example of "chemiluminescence". This is when a chemical reaction yields a product in an electronically excited state (at least one electron in the product is at a level above the ground state). The excited product loses energy in the form of a photon of light when the electron drops to the ground state level. In the case of luminol the reaction is an oxidation under alkaline conditions and the reaction stops when either all the luminol, all the oxidising agent or all the alkali has been converted
