摘　　要：用TPD做空穴传输层 ,8 羟基喹啉铝做发光层 ,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。The electroluminescent characteristics of the organic thin film device used TPD as the hole transproting layer and 8 hydroxyquinoline aluminum as the emetting layer were measured.The mechanism of current transport in the organic thin film device was analysed.That is that the thermal electron injection effect,space electric charge restrict effect,tunnelling effect and resistant effect influenced the current corresponding electroluminescence.\;
