制作了HAT-CN作为空穴注入层的蓝、黄二基色分离的堆叠式高效有机发光二极管,器件结构为:ITO/2-TNATA或HAT-CN(x nm)/NPB(25nm)/ADN(30nm)∶TBPE(2%)∶DCJTB(1%)/Alq3(20nm)/LiF(1nm)/Al(100nm)。实验结果表明,HAT-CN对载流子的注入和色纯度的影响很明显。相比于传统器件将CuPc和2-TNATA作为空穴注入层,HAT-CN作为空穴注入层得到了更高的效率和色纯度,CIE色坐标x=0.330 9,y=0.347 2,电流效率达到6.4cd/A。
HAT-CN was used as a hole-injecting layer of blue and yellow primary color separation of stacked high-efficiency organic light emitting diode device structure is: ITO / 2-TNATA or HAT-CN (xnm) / NPB (25nm) / ADN 30 nm): TBPE (2%): DCJTB (1%) / Alq3 (20 nm) / LiF (1 nm) / Al (100 nm). The experimental results show that the effect of HAT-CN on carrier injection and color purity is obvious. Compared with the conventional devices using CuPc and 2-TNATA as the hole injection layer, HAT-CN obtained higher efficiency and color purity as the hole injection layer. CIE color coordinate x = 0.330 9, y = 0.347 2, current efficiency Reached 6.4cd / A.
