Electrochemiluminescence (ECL) is an electrochemical technique
combining the electrochemical reaction with luminescent detection.
The electrochemical reaction can lead to the formation of an exited
species, which then emits an optical signal for the detection of
the analyte and study of the ECL mechanism. Since the discovery
of light emission of Grigard compounds in 1927 and luminol
in 1929 at different applied potentials, many ECL emitters have
been presented, which promotes the quick development of ECL ...
