Abstract:

Electrochemiluminescence (ECL) is a technique by which a chemiluminescent reaction is generated from reagents produced in the vicinity of an electrode surface when a potential is applied. ECL methods have more significiant advantages over more convential chemiluininescent techniques. In particular, the necessary reactants are produced in situ at a given electrode, enabling the reaction to be controlled through small changes in the applied potential. Furthermore, since light emission is located only in the immediate vicinity of the electrode surface, light colletion is not only efficient but facile.
