Popis: A white organic light-emitting device was realized by using TBPe and DCJTB as fluorescent dopant.The configuration of the devices is ITO/2T-NATA(15 nm)/NPB(25 nm)/ADN∶TBPe[(20-x) nm],ADN∶TBPe∶DCJTB(x nm)/Alq3(20 nm)/LiF(1 nm)/Al(100 nm),and the ADN∶TBPe/ADN∶TBPe∶DCJTB layer are used as emitting layer.The emission properties of devices by adjusting the thickness of ADN∶TBPe∶DCJTB layer has been researched.The results show that when the thickness of the ADN∶TBPe∶DCJTB layer gradually ranges from 2 nm to 8 nm,the electroluminescence spectra shift from blue-light region to white-light region.A white light with CIE coordinates of(0.38,0.34) was achieved when the ADN∶TBPe∶DCJTB layer was 8 nm,which is located in the white-light region.
