โœฆ Synopsis


A stochastic model for luminescence quenching in monodisperse micellar systems is treated without any restriction on the intensity of irradiation. Both time-resolved and steady-state observables are calculated. It is found that the luminescence intensity is given by the convolution product of the sample response function of the system corresponding to the &pulse excitation and the instrument response function only in the limit of low excitation efficiency. It is shown that one of the basic assumptions of the original stochastic model that a micelle should contain at most one excited probe is not necessary provided intramicellar quenching follows pseudo-first-order kinetics.
