Chemiluminescence and Bioluminescence

Abstract

Abstract Chemiluminescence and bioluminescence are terms that refer to the same physical process of light emission without heat. Bioluminescence is the process by which a living system or components isolated from a living system, such as a firefly tail, carry out a series of reactions that result in emission of light. Chemiluminescence is the same kind of process, but involving molecules that are not of biological origin. Chemiluminescence should be distinguished from incandescence, which occurs at high temperatures. Both bioluminescence and chemiluminescence are well known to the public, and both hold great fascination for all observers. Light without heat has intrigued people since the beginning of recorded history, and surely before.
