ABSTRACT:
An organic light emitting device having a phase-separated light-emissive layer comprising:a charge transport phase comprising a charge transport material; andan emitting phase, the emitting phase comprising a plurality of discrete emissive domains dispersed in the charge transport phase, each emitting domain comprising a host material and one or more metal complexes for emitting light by phosphorescence;wherein the charge transport material has a T1 energy level lower than the T1 energy level of the metal complexes and the host material has a T1 energy level higher than the T1 energy level of the metal complexes.
