DossierLuminescence spectroscopy for the first time by Radziszewski [2] in 1877, more specifically the green light emitted from lophine when reacting with oxygen, the term "chemiluminescence" was not introduced until 1888. Wiedemann defined the term "luminescence" (Greek: Lucifer, light bearer) in order to distinguish between light emission from thermally excited substances and light emission from molecules excited by other mechanisms without increasing their average kinetic energy [3]. He classified luminescence phenomena into six different kinds, according to the way of excitation: photoluminescence caused by the absorption of light, electroluminescence produced in gases by an electric discharge, thermoluminescence produced by slight heating, triboluminescence as a result of friction, cristalloluminescence as a result of crystallization, and chemiluminescence caused by a chemical reaction.
