Abstract	A series of rare earth ternary compounds of Tb1-XEu,(TTA)(3)Dipy (HTTA = thenoyltrifluoroacetone, Dipy = 2,2(')-dipyridyl) have been synthesized, and the characteristics of the compounds have been performed by DTA-TG, IR, UV and fluorescence spectroscopy. Photoluminescence measurements indicated that the complexes of Eu(III) emit strong red luminescence under UV radiation. IR spectra suggest that complexes have been successfully synthesized, and TG curves indicate that the complexes are stable up to a temperature of about 220 degrees C. The Eu complex was blended with poly(N-vinylcarbazole) (PVK) and spin coated into films, and electroluminescence devices with the structure of Indium Tin Oxide (ITO)/PVK:Tb1-xEux(TTA)(3)Dipy/BCP(2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline)/ aluminum quinoline (AlQ)/Al were fabricated, the luminescence of Eu3+ complexes enhances after doping with Tb3+. Therefore, it may be an effective method to improve the EL intensity of the lanthanide complex. (C) 2007 Elsevier B.V. All rights reserved.
