Abstract

Pure red organic light-emitting diodes based on a dinuclear europium complex with a structure of (TTA)₃Eu(PYO)₂Eu(TTA)₃ (TTA = thenoyltrifluoroacetonate, PYO = pyridine N-oxide) were presented. The devices showed pure red emission at a peak wavelength of 612 nm with a full width at half maximum of 3 nm, which is a characteristic emission from Eu³⁺ ion based on ⁵D₀ →⁷F₂ transition. The maximum brightness and electroluminescent (EL) efficiency reached 340 cd/m² at a driving voltage of 19 V and 2.4 cd/A (0.78 lm/W) at a current density of 0.14 mA/cm², respectively.
