摘要：

Green phosphorescent top-emitting organic light-emitting diodes (TOLEDs) based on a single ultrathin non-doped emissive layer (EML) are investigated for utilizing the cavity standing wave effect to enhance device performance. Furthermore, double ultrathin non-doped EMLs separated by a bi-layer structure is introduced to balance charges and further improve the efficiency. © 2014 Society for Information Display.
