ORGANIC ELECTROLUMINESCENT DEVICE WITH ENERGY HARVESTING

摘要

Provided herein is an organic light-emitting device and a method of construction thereof. The organic light-emitting device comprises an anode, a cathode, and at least two light-emitting layers located between the anode and the cathode. At least one of the light-emitting layers comprises a host compound having distributed therein a first compound capable of phosphorescent emission at room temperature and a second compound capable of phosphorescent emission at room temperature that has a peak emission wavelength at least 10 nm higher than the first compound.
