The concentrations of Eu2+/Dy3+ (in mole% of the Ba amount) ranged from 0.1/0.1 to 1.0/3.0. The electronic and defect energy level structures were studied with thermoluminescence (TL) and different synchrotron radiation spectroscopies: UV-VUV excitation and emission, XANES and EXAFS. Theoretical calculations using the Density Functional Theory (DFT) were carried out in order to compare with the experimental data.

    Abstract: Rare earth complexes were synthesized and doped into polymers resulting in luminescent films. The obtained systems were characterized with elemental analysis, IR, TGA/DTG and XRD techniques. Photoluminescence properties were investigated and processes of energy transfer and sensitization were studied. Monochromatic emissions of obtained polymeric systems enabled their potential applications in multicolor displays because of the primary colors emitted by TR3+: red (Sm3+ and Eu3+), blue (Gd3+) and green (Tb3+). The polymer matrix performs an essential role in the luminescent sensitization processes for systems containing Sm3+, Eu3+, Gd3+ and Tb3+, therefore the overall systems act as Light Conversion Molecular Devices (LCMDs).

In: INTERNATIONAL CONFERENCE ON ADVANCED MATERIALS, 11th, September 20-25, 2009, Rio de Janeiro, RJ. Abstract... 2009.

    Abstract: Barium aluminates doped with divalent europium and trivalent dysprosium were prepared with the combustion method and then incorporated with silica using the microemulsion method. The incorporated phosphor particles showed improved water resistance, preserving much of the prior persistent luminescence properties even after interaction with water whereas the nonincorporated particles loosed the original persistent luminescence. The infrared absorption spectroscopy, X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and photoluminescence studies were used to characterize the phosphors. The pH of the phosphor-water mixture after the reaction with water was measured to compare the water resistance of the materials. The photoluminescence of the incorporated BaAl2O4:Eu2+,Dy3+ with water modified slightly the 4f6 5d1 →4f7 transition of Eu2+, however.

In: INTERNATIONAL CONFERENCE ON ADVANCED MATERIALS, 11th, September 20-25, 2009, Rio de Janeiro, RJ. Abstract... 2009.

    Abstract: – Nafion-SiO2 hybrid membranes were prepared by the incorporation of SiO2 into commercial Nafion 115 for applications as electrolytes in proton exchange membrane fuel cells (PEMFC) operating at high temperature (~130ºC). These hybrids were produced by conventional in-situ sol-gel method using Tetraethyl Ortosilicate (TEOS) as the silicon precursor, and some synthesis parameters, such as the nature of alcohol (methanol, ethanol, and 2-propanol) used as solvent in the sol-gel reaction were evaluated.

In: INTERNATIONAL CONFERENCE ON ADVANCED MATERIALS, 11th, September 20-25, 2009, Rio de Janeiro, RJ. Abstract... 2009.

    Abstract: Nafion-Titania composite membranes prepared either by casting or by sol-gel route have been studied as electrolytes for Proton Exchange Membrane Fuel Cell (PEM Fuel Cell) at high temperatures (130 ºC). Small angle x-ray scattering (SAXS), scanning electron microscopy (SEM), energy dispersive analysis using x-rays (EDAX) and impedance spectroscopy (IS) were employed to investigate the composite properties. The cast-composite membrane has a heterogeneous distribution of titania particles in the film, whereas the solgel-composite has a well-dispersion of the inorganic phase. The former composite have higher proton conductivity, while the latter has lower proton conduction, owing to the high tortuosity imposed by the dispersed insulator nanoparticles.

A Ptsub(3)Sn/C electrocatalyst with superior activity toward direct ethanol fuel cells. In: INTERNATIONAL CONFERENCE ON ADVANCED MATERIALS, 11th, September 20-25, 2009, Rio de Janeiro, RJ. Abstract... 2009.

    Abstract: – A carbon-supported binary Pt3Sn catalyst was prepared using a modified polymeric precursor method. This material was characterized using X-ray diffraction (XRD), and the results showed that Pt3Sn is the dominant phase. The transmission electron microscopy showed good dispersion of the electrocatalyst and small particle sizes (3.6 nm ± 1.1 nm). The polarization curves for a DEFC using Pt3Sn/C as the anode presented an improved performance compared to that with PtSn/C E-TEK. The maximum power density for Pt3Sn/C electrocatalyst (55 mW cm-2) is nearly twice as great as that of PtSn/C E-TEK electrocatalyst (33 mW cm-2). This behavior may be explained by an electronic effect which is responsible for the increasing in the efficiency toward EOR as indicated in the literature.
