The College of Education for Pure Sciences at the University of Basrah  organized a scientific lecture entitled (Chemical luminescence (cold light) and its measurement devices)
The lecture presented by the student (Karrar Razzaq Hassan) included the study of chemical luminescence, which is a light emission produced through a chemical reaction between two or more substances that results in chemical fluorescence without the need for an external source of excitation such as light or heat, etc. Therefore, it is called cold light. This phenomenon occurs when an electron is excited. And more in the atom by chemical reaction to a high-energy state, which then loses its excess energy quickly producing a photon of light up to the region.
