abstract

  • AbstractGreen 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.
