1. An organic light emitting device, comprising:
- an anode, a cathode, and an emissive layer between the anode and cathode, wherein the emissive layer comprises a host material, a luminescent emissive molecule present as a dopant in said host material, and an intersystem crossing agent which transfers energy to the luminescent emissive molecule, wherein the luminescent emissive molecule exhibits luminescence when a voltage is applied across the anode and the cathode.

Abstract
Organic light emitting devices are described wherein the emissive layer comprises a host material containing a fluorescent or phosphorescent emissive molecule, which molecule is adapted to luminesce when a voltage is applied across the heterostructure, wherein an intersystem crossing molecule of optical absorption spectrum matched to the emission spectrum of the emissive molecule enhances emission efficiency.
