制备了一种新型的黄光器件,其结构为:ITO/2T-NATA(15 nm)/NPB(50 nm)/ADN(20 nm):2% DCJTB:2% TBPe/AlQ (x)/LiF (5 nm)/Al (100 nm) (x=10 nm, 15 nm, 20 nm, 25 nm, 30 nm),通过对不同AlQ厚度的黄光器件的性能如发光光谱、效率、亮度-电压曲线进行比较发现AlQ厚度为20 nm时,发光强度、效率和亮度都是最好的,而发光颜色几乎不发生改变.

In this paper,yellow-OLEDs were fabricated by vacuum evaporation method,and the structure is as follows: ITO/2T-NATA(15 nm)/NPB(50 nm)/ADN(20 nm):2% DCJTB:2% TBPe/AlQ(x)/LiF(5 nm)/Al(100 nm) (x=10 nm,15 nm,20 nm,25 nm,30 nm). The characteristics of yellow-OLEDs with various thickness of electron transport layer (ETL) were compared,such as luminescence spectra,electroluminescent efficiency and luminescence-volte(L-V) etc. From the results,we can see that when the thickness of AlQ layer is 20 nm,electroluminescent intensity,efficiency and luminescence brightness are the best,but the peak position of light-emitting don′t change.
