【摘要】报道了一种含Sc(DBM)3bath的有机发光二极管(OLED)的界面激基复合物发光,器件结构为ITO/TPD/Sc(DBM)3bath/LiF/Al,其中TPD和Sc(DBM)3bath分别为空穴和电子传输材料。这种电致发光(EL)发射主峰位于597nm,最高亮度接近200cd/m2,这种发射来自于TPD和Sc(DBM)3bath界面处两个功能层的相互作用产生的激基复合物。同时该LED在紫外光照射下还表现出明显的光伏特性。更多还原

【Abstract】 An exciplex emitting OLED with the structure ITO/ TPD/ Sc（DBM）₃bath /LiF/Al was studied, in which Sc（DBM）₃bath is used as electron transport layer and TPD as hole transport layer. EL peak of the device locates at 597 nm that comes from the interfacial exiciplex between TPD layer and Sc（DBM）₃bath layer. This device also shows obvious photovoltaic characters under UV light irradiation.更多还原
