Aluminum/MoO3 anode thin films： an effective anode structure for high- performance flexible organic optoelectronics

We report AI/MoO3 thin film used as a complex anode in high-performance OLEDs.The unique efficacy of the device was found to result from the enhanced injection of holes into the commonly used hole-transporting molecules due to a large reduction in the interface dipole at the anode/organic interface.The superior optical characteristics are attributed to a strong cavity effect.Due to the ease of processing Al/M0O3 we successfully demonstrated large-area flexible OLEDs on plastic substrates with uniform emission.
