Quenching effects in organic electrophosphorescence
TL;DR: In this paper, the authors examine various electronic processes that underlie the quenching of the emission from highly efficient phosphorescent and electrophosphorescent organic solid-state molecular systems, as a function of electric field.

Magnetic hyperfine modulation of charge photogeneration in solid films of Alq3
TL;DR: Magnetic fields were found to increase photoconduction in tris-(8-hydroxyquinolinato) aluminum (III) (Alq 3 ) by up to 6% at about 100 mT.

Electric field effect on luminescence efficiency in 8-hydroxyquinoline aluminum (Alq3) thin films
TL;DR: In this paper, the dependence of luminescence quenching on excitation wavelength and electric field is attributed to field-assisted hopping separation of charge in localized excited states in thin films made from common organic electroluminescent material of aluminum (III) 8-hydroxyquinoline (Alq3) is reported.

Electromodulation of Luminescence in Organic Photoconductors
TL;DR: In this paper, a physical interpretation of the luminescence of organic photoconductors is proposed on the basis of the Onsager and macrotrap models, and it is found that EFEL is, in major part, due to the field-induced change in the hopping rate of optically excited charge carriers between localized sites (microtraps) forming an extended defect (macrotrap) for molecular solids with excited states characteristic of neutral Frenkel excitons, whereas the field modification of the carrier diffusion in the separation process seems to be of crucial importance for the

Electric field-assisted dissociation of singlet excitons in tris-(8-hydroxyquinolinato) aluminum (III)
TL;DR: In this paper, a model based on the electric field dependence of electro-modulated fluorescence and steady-state photoconduction in films of tris-(8-hydroxyquinolinato) aluminum (III) (Alq3) was proposed to account for the decrease in electroluminescence quantum efficiency of Alq3-based organic light-emitting diodes at high electric fields.
