摘要

以铱配合物红色磷光体Ir(piq)

( acac)为掺杂剂

制备了基于CBP材料的一系列红色电致磷光器件(PLED)

其结构为ITO/CuPC(1 nm)/Ir(piq)

(acac) ∶ CBP(25 nm)/BCP(10 nm)/Alq

(35 nm)/LiF(1 nm)/Al(100 nm)

对4种不同的掺杂剂浓度进行了比较

研究了它们的电致发光特性。得出了Ir(piq)

(acac)的最佳掺杂比为8%

此时器件的色坐标都非常接近标准红色

且色纯度超过了98%以上;在16 V时

色坐标为(

=0.67

=0.32)

色纯度为99.74%

基本满足了全色显示对红色发光的要求。
