Title

Exciton migration with end detectors: calculation of time-dependent luminescence

Abstract

We present explicit plots of the time dependence of the detector luminescence intensity in surface quenching observations. They are obtained with the aid of numerical inversion methods applied to exact consequences of a master-equation theory of exciton migration. The existing disparity in reported values of the singlet diffusion constant in aromatic hydro-carbon crystals is one of the main issues addressed. It is shown how the theory can be used to extract the exciton diffusion constant without prior knowledge of the (detector) trapping rates, by combining information obtained from steady-state (yield) and time-resolved experiments.
