Item type:Publication, Optical properties of Cu0.95Pt0.05Fe0.97Sn0.03O2 for p-type transparent conducting oxide materials(2013-08-30); ; ; The Cu<inf>0.95</inf>Pt<inf>0.05</inf>Fe<inf>0.97</inf>Sn<inf>0.03</inf>O<inf>2</inf> sample has been synthesized by a solid-state reaction to investigate optical properties of materials of transparent conducting oxide. Crystal structure was characterized by XRD. The Seebeck coefficient and electrical conductivity were measured in the high temperature (300 to 860 K), while the XPS and UV-VIS-NIR spectra were analyzed at room temperature. The XRD peaks confirm the samples forming the delafossite structure phase. The Seebeck coefficient reveals the samples displays the p-type conducting. The XPS spectra show the Sn2+ state stabling in this compound. The optical direct gap is 3.45 eV as a visible-transparent material. These results support that the Cu<inf>0.95</inf>Pt<inf>0.05</inf>Fe<inf>0.97</inf>Sn<inf>0.03</inf>O<inf>2</inf> oxide compounds, of which the Cu<sup>1+</sup> and Fe<sup>3+</sup> sites are substituted by the Pt<sup>1+</sup> and Sn<sup>2+</sup> ions respectively, are p-type transparent conducting oxide materials. © (2013) Trans Tech Publications, Switzerland. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Kinetics and thermodynamics of the formation of MnFeP4O 12(2010-01-14); The kinetics and thermodynamics of dehydration and intermolecular polycondensation reactions of Mn<inf>1/2</inf>Fe<inf>1/2</inf>(H <inf>2</inf>PO<inf>4</inf>)<inf>2</inf> ·H<inf>2</inf>O and Mn <inf>1/2</inf>Fe<inf>1/2</inf>(H<inf>2</inf>PO<inf>4</inf>)<inf>2</inf> were studied under nonisothermal heating by thermogravimetry (TG). On the basis of three calculation procedures and 24 kinetic mechanism functions, kinetic triplets (E, A, kinetic model) using the Arrhenius equation were calculated for both processes. The comparison of the results obtained with these calculation procedures show a strong dependence on the selection of the mechanism function for the process. The thermodynamic functions (ΔH*, C<inf>p</inf>, ΔG*, and ΔS*) of both reactions are calculated from differential scanning calorimetry (DSC) experiments. Kinetic and thermodynamic results indicate that the polycondensation step has a lower rate and is a stronger reaction than the dehydration step and corresponds to the breaking of the strong hydrogenbonded P-OH group, in connection with the polycondensation reaction, which confirms that the decomposition product (manganese iron cyclotetraphosphate, MnFeP<inf>4</inf>O<inf>12</inf>) was obtained. © 2010 American Chemical Society.
