Abstract: An Electroluminescent device with PVK film doped with Eu(TTA)3 Phen and PBD was fabricated. The device structure of glass substrate/indium tin oxide/PPV/PVK∶ Eu(TTA)3 Phen∶PBD/Alq3/Al was employed. A sharply red electroluminescence with a maximum luminance of 56.8 cd/m2 at 48 V was achieved.

Key words: Electroluminescence, Europium complex, Red emission, Doping
