Paper Abstract
This work we presents a detailed result of Organic Light Emitting Diodes based on europium complex as emitting layer, the tris (dibenzoylmethane) – mono (4,7-dimethylphenantroline) europium (III) – Eu(DBM)3phen. The electrical d.c. and a.c. behavior is analyzed and correlated with the electroluminescence data. The electroluminescence spectra show the Eu3+ ion transitions, with the main emission at 612 nm. The driving voltage is about 20 V although the electrical current is only 0.1 mA (Wall Plug Efficiency up to 4×10-3 %). Under some conditions, emissions from others organic emitters can be observed. A model considering the charge confinement and the materials energy levels is proposed and discussed.
