title: Nanoscale heterogeneity and light-emission dynamics in solution-processed phosphorescent organic light-emitting devices.
abstract: Spatial and temporal heterogeneities observed by optical microscopy in the electroluminescence of polymer-based light-emitting diodes doped with phosphorescent iridium complexes are associated with biased voltage-dependent nanoscale structural relaxation of the host polymer matrix.
