Electrochemiluminescence or electrogenerated chemiluminescence (ECL) is a phenomenon in which an excited state—formed by an electron-transfer reaction between electrogenerated species in the vicinity of a working electrode—emits light. Although the first detailed studies of ECL were reported in the 1960s, ECL publications have revealed an exponential growth worldwide thanks to advances in nanotechnology, photoelectrochemistry, and spectroscopy.
