基于稀土镱配合物的有机电致发光器件
Jilin Normal University Journal(Natural Science Edition)（2009）
Abstract
利用真空气相沉积法制备了基于稀土镱配合物的有机电致发光器件,其器件结构为ITO/m-MTDATA/TPD/TPD:Yb(DBM)3Pyphen/Yb(DBM)3Pyphen/BCP/LiF/Al.其中TPD为空穴传输层,Yb(DBM)3Pyphen为发光层,BCP为激子阻挡层.该器件的发射是来自Yb(DBM)3Pyphen与TPD形成的激基复合物的发光.在直流电压的驱动下,11 V时最高亮度和效率分别为103 cd/m2和0.47 cd/A,色坐标为(0.346 0.32).
