摘　　要：探讨了发光层厚度以及复合阴极材料对聚合物电致发光器件稳定性的影响,并通过对同一器件在不同初始亮度下的寿命进行测试比较,得到了该器件寿命的加速老化因子。然后,通过计算得知,结构为ITO/PEDOT:PSS/MEH-PPV/Ba/Al的聚合物电致发光器件在初始亮度为100 cd/m2情况下的寿命高达10 124 h,基本上达到了实用化要求。The effects of light-emitting layer thickness and multilayer cathode components on the stability of polymer light-emitting device（PLED） were studied.And,the accelerated aging factor of PLED was obtained by measuring and comparing the working life of the PLED at different initial luminance.With the obtained accelerated aging factor,the working life of the PLED with a structure of ITO/PEDOT： PSS/MEH-PPV/Ba/Al at an initial luminance of 100 cd/m2 is calculated to be 10 124 h,roughly fulfilling the requirement of practical applications.
