摘要
为了研究PMOLED器件的物理特性,在Alq3主体材料中掺杂C545制备了PMOLED发光器件,其单象素结构为TO(120nm)/CuPc(12nm)/NPB(50nm)/Alq3:C545(30nm)/LiF(1nm)/Al(200nm),色坐标为(0.276,0.589)。该器件的载流子注入模型,在起亮前符合热发射注入模型;起亮后满足遂穿注入模型。PMOLED能较好地满足朗伯定律,并具有响应速度快,视角宽,色彩保真度高等特性。
This thesis focuses on the luminescence characteristics of the PMOLED (Passive Matrix organic light emitting device). Using Alq3 which was doped with C545, we fabricated PMOLED with the structure(ITO(120nm)/Cu Pc(12nm)/N PB(50nm)/Alq3C545 (30n m)/LiF (1 n m)/Al(200nm)) of a single pixel. The analysis firstly illustrates that carrier injection mode is judged by threshold voltage (before turning on, it matches the model of Injection bythermionic emission, and after that, it satisfies the model of Injection by tunneling through the triangular barrier). Secondly, PMOLED matrix device follows Lambert Law and has high-speed response in theory. Thirdly, it has characteristics of wideviewof angleand high fidelityof chromatics etal.
