基于Alq2（DBM）的白色有机电致发光器件

摘要

We fabricated non-doping bilayer White Organic Light-Emitting Diode（WOLED） with Alq2（DBM）.The structure of device was ITO/NPB（44 nm）/Alq2（DBM）（66 nm）/LiF（0.8 nm）/Al（100 nm）,with a lower turn-on voltage at 6 V.WOLED exhibit a maximum luminance of 468 cd/m2 and current density was 311 mA/cm2,and the Commission International De L＇ Eclairage of（0.32,0.38） at 11 V.%利用新型铝配合物Alq2（DBM）制备了非掺杂型的双层有机电致白光器件,其结构为ITO/NPB（44 nm）/Alq2（DBM）（66 nm）/LiF（0.8 nm）/Al（100 nm）.该器件6 V电压下启亮,在11 V时实现了白光发射,色坐标为（0.32,0.38）.器件的最大发光亮度达到468 cd/m2,对应的电流密度为311 mA/cm2.
