LUMINESCENCE QUENCHING IN MICELLAR CLUSTERS AT SHORT TIMES AND OR HIGH QUENCHER CONCENTRATIONS/

A stochastic model for luminescence quenching in clusters of monodispe rse micelles is developed and exactly solved for the case where both p robes and quenchers can migrate between individual micelles that are i n direct contact during the excitation lifetime. The model provides a short-range approximation to the survival probability being accurate a t short times and/or at sufficiently high quencher concentrations, whe n the reactants make at most one step before reacting.
