-1 . Medidas resolvidas no tempo indicaram que a microestrutura da matriz polimerica nao afetou as propriedades eletro-opticas das blendas. The complex tris(thenoyltrifluoracetonate)(2,2’-bipyridine)europium(III), Eu(tta) 3 bipy, was synthesized and assessed for luminescence behavior. The emission of its blends with poly(9vinyl carbazole) (PVK-Eu), varying in composition from 1 to 8% (Eu(tta) 3 bipy/PVK, m/m) showed PL at 425 nm and at 613 nm, with intensities which depended on the blend composition. Double-layer LED devices with configuration ITO/PEDOT-PSS/Blend/Ca-Al emitted red light with turn-on voltages of 9 V and emission maxima at 617 nm; its luminance efficiency was 0.04 cd A -1 . Time resolved measurements indicated that the microstructure of the matrix had practically no effect on the electro-optical properties of the blends.
