By generating the redox species at potentials corresponding to
the foot of polarographic waves, the conversion of electrical energy
into light at efficiencies greater than 100°/o is shown to be thermodynamically
permitted. It is also shown that criteria for this are
not met by presently available redox chemiluminescent systems,
and the ionquenching efficiency of the electrode is quantitatively
evaluated as a function of redox annihilation rate constant, luminescor
parent compound concentration, molecular 1size, and applied
