| 摘 要： | 我们研制了用有机材料Tb(AcA)3·phen作为发射层的绿色发光二极管,两层结构为玻璃衬底ITO/芳香族二胺类衍生物TPD/Tb(AcA)3·phen/A1。各功能层均用真空热蒸发的方法制备。在正向直流偏压驱动下获得了Tb3+的特征发光,同时还发现一个峰位425um的蓝光发射,它来源于空穴输运层TPD。在室温条件下器件的阈值电压为4V,当驱动电压提高到16V时,器件的最高发光亮度达到200cd/m2,同时在相同条件下制备了结构为玻璃衬底ITO/芳香族二胺类衍生物TPB/Tb(AcA)3·phen/A1的器件,通过对两种器件光谱及电学特性的测量、比较与分析,探讨了有关稀土有机电致发光的发光机理等问题。

| Abstract: | Organic EL devices having Tb3+ complex as an emitter have been reported by our group. In this paper we examine the properties of organic EL device with diamine as a hole transport layer, TPD:N,N'-diphenyl-N,N'-(3-methyl)phyla-1,1'-4,4'-biphenyl-4,4' -diamine. Stronger Tb3+ EL emission with lower blue emission from HTL layer was obtained. It is also found that the devices have better I-V character and lower threshold voltage. |
