Microcavity effect in a single‐layer polymer light‐emitting diode

Abstract
The luminescence of conjugated polymers is of great interest both as a tool for the investigation of electronic processes in these materials and ecause of its significance for applications in light‐emitting devices. The first demonstration of an electroluminescence‐pumped microcavity using a conjugated polymer is reported, representing the first step towards the development of an electrically or optically pumped organic laser.
