摘要
用TPD作空穴传输层、8-羟基喹啉锌作发光层 ,制备了有机薄膜器件 ,测量了其电致发光特性。分析了该器件的电流输运机理 ,认为该有机薄膜器件在电致发光时流过器件的电流受热电子注入效应、空间电荷限制效应、隧穿效应及器件电阻效应的影响。
The electroluminescent characteristics are measured of the organic thin film device using TPD as the hole transporting layer and 8-hydroxyquinoline zinc as the emitting layer. The mechanism of current transport in the organic thin film device is analysed. It is shown that the current generated during electroluminescence is dependent on such factors as the thermal electron injection effect, space electric charge restrict effect, tunnelling effect and resistant effect.
