【摘要】 采用半透明的镁银合金阴极成功制备了直流驱动的绿光透明有机电致发光器件,并在此基础上,提出利用半透明的镁银合金中间连接层连接两个发光子单元的新型器件结构,从而成功实现了交流驱动的绿光透明有机电致发光器件。在铟锡氧化物和镁银合金两侧的出光方向上,器件的光谱完全一致,最大亮度分别达到1 374 cd/m~2和283 cd/m~2,最高效率分别达到26.1 cd/A(8.1 lm/W)和3.5 cd/A(1.7 lm/W),铟锡氧化物一侧的性能较好是由于铟锡氧化物电极和镁银合金中间连接层的透过率不同形成的。在低频交流电驱动下,器件的两个发光子单元交替发出绿光;而在高频交流电驱动下,由于人眼无法分辨交替点亮时的闪烁,两个发光子单元对于人眼而言则是同时且稳定地发出绿光。更多还原

【Abstract】 Direct current driven green transparent organic light-emitting device utilizing transparent Mg∶Ag cathode was fabricated. Then, novel device structure employing transparent Mg∶Ag interconnecting layer to connect two light-emitting units was proposed to realize alternating current driven green transparent organic light-emitting device(AC-TOLED). The spectra of AC-TOLED were almost identical in the direction of light output on indium tin oxide(ITO) and Mg∶Ag sides. The maximum brightness was 1 374 cd/m~2 and 283 cd/m~2, respectively. And the maximum efficiency was 26.1 cd/A(8.1 lm/W) and 3.5 cd/A(1.7 lm/W), respectively. The higher performance of ITO side was caused by the different transmission of ITO electrode and Mg∶Ag interconnecting layer. Under low frequency alternating current, the two light-emitting units of AC-TOLED emitted green light alternately. However, the two light-emitting units of AC-TOLED emitted green light simultaneously for human eyes under high frequency alternating current, because human eyes cannot distinguish the flicker of each unit during alternative emission.更多还原
