This reaction is called as <span>Chemiluminescence. A type of reaction in which light is produced due to chemical reaction. While in case of Phosphorescence and Fluorescence light is emitted due to absorption of photons.
When dianion of luminol is reacted with Oxygen, a unstable peroxide is formed, and elimination of Nitrogen gas takes place with the de-excitation of electrons from higher state to ground state and the energy is released in the form of Blue Light. </span>
