Abstract:
An OLED having an organic layer formed of a dopant and a host, where the organic layer is disposed between an anode and a cathode is disclosed. The dopant's concentration level in the organic layer, along a direction perpendicular to the first and second planar surfaces of the organic layer, defines a novel concentration gradient that enhances the OLED's efficiency.
