Abstract:
Yb(DBM)3(DPEPO), an emitter, was directly synthesized on a substrate by the vacuum co-deposition of the precursor Yb(DBM)3(H2O)2 and the ligand DPEPO. OLEDs incorporating the co-deposited emitting layer (Yb(DBM)3(H2O)2 : DPEPO molar ratio = 1 : 1) achieved an ηEQE value of 0.15% at 1.0 mA cm-2.
