Non-Exponential Decay Curves in Delayed Luminescence

Abstract:

Delayed luminescence, contrary to popular belief, never follows an exponential de-cay law and the way it falls o can be an interesting, inexpensive and non-destructive probe ofboth nonliving and living systems. We discuss the basic ideas involved, deviations from expo-nential decay, new technologies for measurement, and possible applications. For living systemsexhibiting approximately hyperbolic decays, we make a possible connection to old ideas ofSzent-Gyorgyi on charge transfer complexes in biology.
