An Introduction to Chemiluminescence Chemiluminescence is the is the production of light without heat from a chemical reaction. In this reaction, energy is released as electromagnetic radiation in the visible light spectrum. It does not require the absorption of electromagnetic energy to excite molecules into a higher energy state. Instead, the energetics of the reaction itself releases energy as light. This means that there there is an intermediate molecule in an excited state which returns to a lower energy level, releasing its energy in the form of a photon of light. The reaction within a glow stick is a primary example of chemiluminescence. These reactions, which typically involve luminal, have been generally well studied and its applications range from use in forensics for detecting traces of blood, in the pharmaceutical industry for quality control and in clinical services. Chemiluminescence in Glow Sticks Since it’s advent in 1965, glow sticks have been extensively used throughout society, serving a multitude of purposes. For most people, the word ‘glow sticks’ brings to mind little children frantically waving them around on halloween, or perhaps even the idea of a jam-packed neon-lighted nightclub. For major halloween buffs, myself included, the idea of glow sticks brings people back to their childhoods, where glowsticks played a considerable role- serving as a source of entertainment (and light) during halloween and new year parties. However, common uses
