Abstract In this paper, we optimized exciplex-based organic light-emitting diodes (OLEDs) using single-carrier devices to improve carrier balance and identify the location of the carrier recombination region, which can enhance OLED performance. Exciplex-based OLEDs with a Indium Tin Oxide structure / 4,4′,4′'-Tris[(3-methylphenyl)phenylamino]triphenylamine (m-MTDATA) (x nm) / m-MTDATA: Bathophenanthroline (Bphen) (40 nm, 1:1) / Bphen (30 nm) / LiF (1 nm) / Al (80 nm) were fabricated with various thicknesses of the hole transport layers. We controlled the m-MTDATA:Bphen emission layer evaporation rate at 0.8 A/s, which was the best choice for indoor application in our previous study. The maximum OLED current efficiency of 71.5 cd/A at a luminous intensity of 443 cd/m2 and emission wavelength of 552 nm was obtained, which is suitable for indoor power-saving OLED applications. Furthermore, this study used a lower-energy red-doping layer to observe how excitons move in exciplex-based OLEDs when the external electric field increases.

高效激基复合绿色有机发光二极管中激子运动的工艺优化与研究

摘要 在本文中，我们使用单载流子器件优化了基于激基复合物的有机发光二极管 (OLED)，以改善载流子平衡并确定载流子复合区的位置，从而提高 OLED 性能。具有氧化铟锡结构的 Exciplex OLED / 4,4',4''-Tris[(3-methylphenyl)phenylamino]triphenylamine (m-MTDATA) (x nm) / m-MTDATA: Bathophenanthroline (Bphen) (40 nm, 1:1) / Bphen (30 nm) / LiF (1 nm) / Al (80 nm) 被制造成具有不同厚度的空穴传输层。我们将 m-MTDATA:Bphen 发射层蒸发速率控制在 0.8 A/s，这是我们之前研究中室内应用的最佳选择。在443 cd/m2的发光强度和552 nm的发射波长下获得了71.5 cd/A的最大OLED电流效率，适用于室内节能OLED应用。此外，这项研究使用低能量的红色掺杂层来观察当外部电场增加时激子如何在基于激基复合物的 OLED 中移动。
