Abstract

An oxadiazole-functionalized europium β-diketonate complex [(OXD−PyBM)Eu(DBM)3] was designed and synthesized. The double-layer device with the configuration of ITO/TPD (40 nm)/(OXD−PyBM)Eu(DBM)3 (50 nm)/LiF (1 nm)/Al (200 nm) emitted pure bright red light with an emission at 612 nm. An external quantum efficiency of 1.7% and luminance efficiency of 1.9 cd/A at the current density of 3 mA/cm2 were obtained and were significantly improved, in comparison with those of the europium complex without the electron-transporting moiety.

The ITO glass was routinely cleaned by ultrasonic treatment in detergent solutions, followed by being rinsed with acetone, boiled in 2-propanol, and rinsed in methanol and then in deionized water. The glass was dried in a vacuum oven between each cleaning step earlier. The electroluminescent device was fabricated by high-vacuum (2 × 10-6Torr) thermal evaporation techniques. The shadow mask with 3 × 3 mm2openings was used to define the cathodes. The EL spectra were recorded with JY-SPEX CCD-3000 V spectrometer. The current−luminance−voltage characteristics were measured using a Keithley source measurement unit with a calibrated silicon photodiode.
