基本信息
结项摘要
半导体固态照明光源（SSL）有巨大的节能潜力。有机半导体电致发光器件（OLED）比无机LED有明显优势，其新的目标是实现有机SSL。项目将在原基础上，经国际合作对实现白光OLED的SSL的某些关键问题（提高发光效率的机制、大面积均匀稳定发光和器件的长寿命、柔性化等）进行基础研究并有所突破,显示其作为SSL的可能与优势。在设计橙-红色发光层时,在聚合物主体中引入三线态磷光和荧光体,作为敏化剂和发光材料,经多级能量转移得到高的发光效率。在关键的蓝-绿光层中,引入了高效、稳定的Zn(BTZ)2,由于其所处的位置与厚度可控,保证了空穴向橙-红光层的传输及蓝光的有效输出。用电刻法对阳极"分割",将分割单元并联后可得到连续均匀的面光源。采用内置镀膜和旋涂设备的充氮手套箱,使制备封装全过程严格避氧和水,减少了膜的缺陷,改善了层间的界面状态。用PECVD制备介质膜与有机膜的交替层能阻隔水氧并实现器件柔性化
