摘要

We report on red phosphorescent trilayer organic light-emitting field-effect transistors (LEFETs), which exhibit ambipolar transport characteristics but strong emission in the unipolar hole regime, with an exceptionally wide recombination zone of 60-70μm and a maximum external quantum efficiency of 0.21%. From the results of detailed electroluminescence characterization, we clarify how the energy-level matching condition and transport geometry of the heterostructure govern the charge distribution and recombination, and affect the overall device performance.
