| Abstract: | A novel rare earth complex of Eu ion with 2-benzoylbenzoic acid and 1,10-phenathrolinephen (Eu(o-BBA)3 (phen)) was synthesized and used as a dopant to fabricate efficient electroluminescence(EL) devices. It was doped into poly(N-vinylcarbazole) (PVK) and spin coated into films. Devices using organic layer Alq3 (or inserted hole blocking layer BCP) and inorganic layer ZnS as electron transporting layer respectively were fabricated. The luminescence properties of the single-layer decvice A (ITO/PVK : Eu/Al) and the organic-inorganic heterostructure device were analyzed. It was found that the device using ZnS as the electron transporting layer has higher brightness and lower threshold voltage while maintains pure emission. |
