Chemiluminescence

Chemiluminescence is a process where a chemical reaction produces light without the need for heat. When certain substances react, their molecules release energy. Instead of this energy converting into heat, it excites electrons within the molecules. When these electrons return to their normal state, they release the excess energy as visible light. This phenomenon is responsible for glow-in-the-dark items like glow sticks and bioluminescent organisms such as fireflies. Chemiluminescence is used in various applications, including medical diagnostics and forensic analysis, offering a safe and efficient way to generate light through chemical reactions.
