Abstract

Multilayered organic light-emitting diodes (OLEDs) were fabricated by using the new fluorine derivatives end-capped with arylaminofluorenylethylenes as dopant materials. The device structure was ITO/NPB/15% blue dopants doped in MADN/Bphen/Liq/Al. Among those, a device shows the maximum luminance of 40800 cd/m2 at 12 V, the luminous efficiency of 12.8 cd/A at 20 mA/cm2, power efficiency of 9.13 Im/W at 20 mA/cm2 and CIE(x,y) coordinates of (x = 0.188, y = 0.372) at 8 V.

摘要

通过使用以芳基氨基芴乙烯封端的新型氟衍生物作为掺杂材料来制备多层有机发光二极管（OLED）。器件结构为ITO/NPB/15%蓝色掺杂剂掺杂在MADN中/Bphen/Liq/Al。其中，一个器件在12V时显示出最大亮度为40800cd/m²，在20mA/cm²时发光效率为12.8cd/A，在20mA/cm²时功率效率为9.13lm/W，在8V时CIE(x,y)坐标为(x = 0.188, y = 0.372)。
