Abstract :
Trivalent dysprosium ion (Dy3+) complex with a structure of Dy(acetylacetonato)3phenanthroline (Dy(AcA)3phen) was synthesized and used as an emitting material in organic electroluminescence (OEL) devices from which a white light emission was observed. A double-layer OEL device with a structure of PVK (100 nm)/Dy-complex (70 nm) was fabricated. The white emission consisted of a yellow band (∼580 nm) and a blue emission band (∼480 nm) corresponding to the 4F9/2→6H13/2 transition and 4F9/2→6H15/2 transition of Dy3+ ion in the complex, respectively.
