我们与器官的多层的量井结构制作一系列样品和 OLED,它由交替的 PBD 和 Alq3 组成。PBD 和 Alq3 是搬运电子的材料,并且 PBD 被用作潜在的障碍层,当 Alq3 被用作潜在的井层和射出的层时。与双层结构相比,有量井结构的器官的样品和二极管的光特征被调查,量井结构帮助精力转在之间很好层和障碍层。量井结构让搬运人在不同的井层分散然后增加激子的数字提高再结合的效率。CLC 数字 O621.22 这个工作被鈥 ? 支持中国(号码 2003CB314707 ) 的 73 鈥 ? 公民钥匙 Basic 研究基础,中国(号码 60576016, 10374001,和号码 10434030 ) 的国家自然科学基础。
We fabricate a series of samples and OLEDs with organic multilayer quantum well structure, which consist of alternate PBD and Alqy Both PBD and Alq3 are electron-transporting materials, and PBD is used as potential barrier layer, while Alq3 is used as potential well layer and emitting layer. Compared with double-layer structure, the luminescent characteristics of organic samples and diodes with quantum well structure are investigated and the quantum well structure helps the energy transfer between well layer and barrier layer. The quantum well structure makes carriers disperse in the different well layers and then increases the number of excitons to enhance the efficiency of the recombination.
