Abstract:OLEDs with configurations of ITO/CuTcPc/NPB/Alq3∶C545T/Alq3/LiF/Al,ITO/CuTcPc/NPB/Alq3∶C545T/Alq3/Al were fabricated using CuTcPc as electron injection layer,NPB as hole transport,layer Alq3∶C545T as emission layer,and Alq3 as hole transport layer.In our experiments,the CuTcPc treated devices have greater luminances than that of the conventional devices.As holes are the majority carriers in these multilayer OLEDs,the increased hole injection should lead an imbalance of carrier and a lower efficiency.But through our experiment,it is found that both the hole injection and the electron injection are increased after CuTcPc surface treatment.CuTcPc surface treatment can not only improve the luminances and the current density,but also can improve the current efficiency of the devices comparing with the conventional devices.
Keywords:CuTcPc                  organic light emitting-diodes                  carrier charge imbalance                  current efficiency
