Singlet exciton energy transfer in organic solids

Abstract A comprehensive review is presented of the experimental data which have been obtained on singlet exciton energy transfer in organic crystals. The usefulness of different types of experimental techniques in elucidating the characteristics of both exciton migration and trapping is discussed, as are the effects of radiative reabsorption on the results obtained by different types of measurements. The importance of activator-induced host traps is stressed and previous data are reinterpreted in terms of such traps.
