Abstract: A white organic light emitting device comprises a first electrode; a hole transporting layer in contact with the first electrode; a second electrode; an electron transporting layer in contact with the second electrode; and an emissive layer between the hole transporting layer and the electron transporting layer. The emissive layer comprises a host, a fluorescent emitter, and a phosphorescent emitter. The fluorescent emitter harvests singlet excitons and emits blue light, and the phosphorescent emitter harvests triplet excitons and emits yellow-amber light.

Abstract: A near-infrared organic light emitting device comprises a first electrode; a hole transporting layer in contact with the first electrode; a second electrode; an electron transporting layer in contact with the second electrode; and an emissive layer between the hole transporting layer and the electron transporting layer, the emissive layer comprising a near-infrared emitter and an emissive host. The emissive host transfers energy to the near-infrared emitter.

Abstract: Organic light emitting devices (OLEDs) with emissive layers containing both phosphorescent Pt complexes and fluorescent emitters, are described. The devices presented employ both fluorescent and phosphorescent Pt complexes in order to redistribute the excited states to primarily reside on known stable fluorescent emitters to achieve high device operational stability but maintain the high efficiency characteristic of phosphorescent OLEDs.
