Title: Organic electroluminescent devices

Abstract

An organic light emitting device is disclosed in which the emissive dopant material in its organic emissive layer is an organic phosphorescent emissive material and a neat film of the organic phosphorescent emissive material is disposed between the organic emissive layer and the anode as an electron blocking layer.
