Electric field-assisted dissociation of singlet excitons in tris-(8-hydroxyquinolinato) aluminum (III)

Results based on the electric-field dependence of electro-modulated fluorescence and
steady-state photoconduction in films of tris-(8-hydroxyquinolinato) aluminum (III)(Alq 3) are
consistent with a model where singlet excitons dissociate into electron–hole pairs through
charge transfer state. Dissociation into free carriers or predominantly geminate
recombination results from this intermediate state. The quantum efficiency of charge
separation is in agreement with predictions based on a model using the three-dimensional …
