Abstract
AbstractBy thinning the metal electrode, the SPP modes of OLEDs can be coupled to the outside surface of the device, where they can be recycled for external emission by simply capping the device with an appropriate absorbing/re‐emission medium. A modest efficiency enhancement has been observed. In addition, such an approach provides double‐emitting OLEDs with a wide‐range color tuning capability, which may be of use for some applications.
