| 摘 要： | 介绍利用优化有机膜厚度的方法,制作了发光效率较高的有机电致蓝光器件.器件的结构为:ITO/2T-NATA/NPB/DPVBi/TPBi/Alq3/LiF/Al,当2T-NATA,NPB,DPVBi,TPBi,Alq3,LiF的厚度分别为15 nm,10nm,20 nm,15 nm,25 nm,0.6 nm时,器件的性能最好.在电压为12 V,电流密度为537 mA/cm2时·亮度达到最大为13 540 cd/m2.在电压为7 V,电流密度为22 mA/cm2时,器件的最大电流效率为4.48 cd/A.且器件的开启电压较低,在4 V工作电压下,亮度达到4.82 cd/m2.电压在5～12 V的范围内,发光色度几乎不随驱动电压或电流密度的改变而改变,稳定在x=0.17,y=0.16附近,处于蓝光中心区域.
