Resumo |
Stacked organic light-emitting devices (OLEDs) based on a europium complex Eu(TTA)(3) (Tmphen) (TTA = thenoyltrifluoroacetone,Tmphen = 3,4,7,8-tetramethyl-1,10-phenanthroline) were fabricated. In this stacked OLEDs, Li:BCP/V2O5 was used the intermediate charge generation layer sandwiched between two identical emissive units consisting of TPD/CBP:DCJTB:Eu(TTA)(3)(Tmphen)/BCP. As expected, the brightness and electroluminescent (EL) current efficiency were approximately enhanced by double times that of conventional single-unit devices. The stacked OLEDs showed the maximum luminance up to 3000 cd/m(2) at a current density of 190 mA/cm(2) and a current efficiency of 14.5 cd/A at a current density of 0.08 mA/cm(2). At the brightness of 100 cd/m(2), the current efficiency reached 10 cd/A at a current density of 1.6 mA/cm2. |
