摘 要: 介绍了有机自旋电子学在有机电致发光二极管(organic light-emitting diode,OLED)中的应用和研究进展,着重讨论了有机自旋阀(organic spin valve, OSV)和有机电致发光的磁效应(magneto-electro luminescence, MEL)在有机电致发光中的应用。利用有机自旋阀效应,可以控制电子的自旋注入。目前已经在室温下得到了有机自旋阀,并且证实了有机材料中的超精细相互作用。利用Al2O3,CuPC等材料对器件进行表面处理可以提高器件的MEL. 利用MEL现象可以研究掺杂器件中的Frster能量传递过程,在较高温度电致发光的MEL研究也取得了一定的进展。利用掺杂磁性纳米线和纳米粒子也可以提高器件的性能。此外,还探讨了有机自旋电致发光可能的发展方向。
关 键 词: 固体发光;有机电致发光;综述;有机自旋阀;巨磁阻

Abstract: This paper introduces the applications and research progress of organic spintronics in organic light-emitting diode (OLED). This paper focused on the application of organic spin valves and magneto-electro luminescence (MEL). The spin injection of the electron can be controlled by organic spin valve (OSV) device. The OSV was obtained at room temperature, and the hyperfine interaction (HFI) was confirmed in OSV device. Using surface treatment by thin materials such as Al2O3 and CuPc can improve the MEL of the device. MEL phenomenon can be used to research Frster energy transfer process in doped devices, and high temperature MEL was also studied. MEL phenomenon can be use to research Frster energy transfer process of the doped OLED devices, and high temperature MEL was also studied. The use of doping magnetic nanowires and nanoparticles can also improve the performance of the device. In addition, the possible development direction of organic spin electroluminescence was discussed.
