• Sol-gel processing of fluoride and oxyfluoride materials

  Fujihara S., Handbook of Sol-Gel Science and Technology: Processing, Characterization and Applications, 2018.07

  　View Summary

  Producing fluoride and oxyfluoride materials is not easy because of the potential toxicity of fluorinated compounds and gases. Sol-gel processing has been used to produce fluoride and oxyfluoride materials in two ways. In the first case, the composition is formed from oxide precursors, followed by a reactive treatment in HF to fluorinate the composition. In the second case, trifluoroacetate precursors or metal alkoxides in trifluoroacetic acid are used to form the gel or thin films directly. The principal motivation for using sol-gel routes to prepare glassy fluorides and oxyfluorides is that they have useful optical applications.

• Ni-doping effect on thermoelectric properties of c-axis-oriented CuFeO<inf>2</inf> ceramics

  Hagiwara M., Tato M., Shiojiri D., Iida T., Fujihara S.

  Journal of Alloys and Compounds (Journal of Alloys and Compounds)  905 2022.06

  ISSN  09258388

  　View Summary

  The combined effect of chemical doping and grain orientation on the thermoelectric properties of delafossite-type CuFeO2 ceramics was investigated. Ni was chosen as the dopant, whereas the reactive templated grain growth method was used for the fabrication of grain-oriented bulk ceramics. Nanorods of Ni-doped α-FeOOH with a nominal Ni content of up to 5 mol% were synthesized by the hydrothermal method and were then used as the template to fabricate Ni-doped CuFeO2 ceramics with a preferred c-axis orientation. The electrical conductivity, Seebeck coefficient, and thermal conductivity of the Ni-doped CuFeO2 ceramics along the in-plane direction (perpendicular to the orientation axis) were measured at temperatures between 300 and 1100 K. Ni doping was found to effectively increase the electrical conductivity and decrease the thermal conductivity, whereas it maintained a high Seebeck coefficient of around 400 μV K−1. Consequently, the c-axis-oriented CuFeO2 ceramics doped with 1 and 3 mol% Ni showed an enhanced dimensionless figure of merit of 0.08 at 900 K.

• Grain-size-insensitive dielectric properties of Sr<inf>0.6</inf>Ba<inf>0.4</inf>Nb<inf>2</inf>O<inf>6</inf> relaxor ferroelectric ceramics with tetragonal tungsten bronze structure

  Tsuchiya M., Fujihara S., Hagiwara M.

  Ceramics International (Ceramics International)  48 ( 5 ) 6819 - 6825 2022.03

  ISSN  02728842

  　View Summary

  The influence of grain size on the dielectric properties of Sr0.6Ba0.4Nb2O6 (SBN60) ceramics with a tetragonal tungsten bronze structure was examined. The conventional and two-step sintering procedures were used to fabricate dense and phase-pure SBN60 ceramics with grain sizes ranging from 2.2 μm to 17.3 μm. In the temperature dependence of the dielectric permittivity, all samples showed a relaxor-like broad dielectric peak with a maximum at around 60 °C. The maximum dielectric permittivity and dielectric maximum temperature of the SBN ceramics were found to be less dependent on the grain size. The reason for the grain-size-insensitive dielectric properties of the SBN60 ceramics is discussed based on the analysis of the dielectric properties and Raman spectra.

• Redox-induced dual optical switching of CaTiO<inf>3</inf>:Pr³⁺ phosphor nanoparticles synthesized by sol–gel method

  Takahashi H., Hagiwara M., Fujihara S.

  Journal of Sol-Gel Science and Technology (Journal of Sol-Gel Science and Technology)   2022

  ISSN  09280707

  　View Summary

  Red-emitting CaTiO3:Pr3+ phosphor nanoparticles were synthesized by a sol–gel method with a final heat treatment at a low temperature of 650 °C. For comparison, the CaTiO3:Pr3+ phosphor was also synthesized by a conventional solid-state reaction method conducted at 1250 °C. The two kinds of resultant CaTiO3:Pr3+ samples were revealed to differ largely in their microstructure and optical properties. Diffuse reflectance and photoluminescence measurements suggested that the sample from the solid-state reaction possessed a larger number of defects, which would deteriorate the optical properties, due to heating at high temperature. On the other hand, the sol–gel-derived sample exhibited much better optical properties and thus it was used for evaluating optical-switching phenomena upon redox treatments. In photoluminescence, three excitation bands were observed at 265, 335, and 375 nm for the red emission of the CaTiO3:Pr3+ sample, and one of them (375 nm) was more effective for inducing luminescence quenching by a reduction treatment at room temperature. A body color of the CaTiO3:Pr3+ sample was also changed from white to light yellow by the reduction due to the enhanced visible-light absorption. Such the dual luminescence/absorption switching was shown to be reversible with a subsequent oxidation and repeatable with a consecutive redox treatment. [Figure not available: see fulltext.]

• Fabrication of meso- and macro-porous Y<inf>2</inf>WO<inf>6</inf>:Eu³⁺ phosphor thin films by Pechini-type sol–gel dip-coating method and their characteristic optical properties

  Ye H., Hagiwara M., Fujihara S.

  Journal of Sol-Gel Science and Technology (Journal of Sol-Gel Science and Technology)  100 ( 2 ) 232 - 243 2021.11

  ISSN  09280707

  　View Summary

  Meso- and macro-porous Y2WO6:Eu3+ phosphor thin films were fabricated on silica glass substrates by a Pechini-type sol–gel dip-coating method. Precursor solutions for coating were prepared by mixing aqueous solutions of metal salts, ethylene glycol, and citric acid with water–alcohol solutions of a nonionic triblock copolymer (P-123) employed as a structure-directing agent. The kind of the alcohol solvents (methanol, ethanol, or isopropanol) and the amount of ethylene glycol were systematically examined because they were found to be major factors that could influence the shape and size of pores formed in the resulting thin films. The transmittance for the visible light was decreased in the thin films having macropores due to the light scattering. The red photoluminescence of the Eu3+ ions could be enhanced in these macro-porous thin films, especially from their surface, by a synergetic effect of increased multiple scattering and suppressed internal reflection of the emission light. The relationship between the microstructure and the optical properties of the porous Y2WO6:Eu3+ thin films was then discussed based on the experimental results. [Figure not available: see fulltext.]

• Fabrication of p-type semiconducting NiCo<inf>2</inf>O<inf>4</inf> thin films using hydroxide nanoplatelet precursors and their application to N749-sensitized photocathodes

  Miyachi M., Hagiwara M., Fujihara S.

  Journal of the Ceramic Society of Japan (Journal of the Ceramic Society of Japan)  129 ( 7 ) 348 - 354 2021.07

  ISSN  18820743

  　View Summary

  NiCo2O4 is promising as one of the p-type oxide semiconductors for practical applications in optoelectronic devices. In this study, we have elaborated NiCo2O4 hexagonal nanoplatelet films and examined their photovoltaic properties. The film fabrication was actually achieved by four steps: the synthesis of hexagonal nanoplatelets of a Ni1/3Co2/3(OH)2 precursor, the dispersion of the nanoplatelets in liquid media, the self-assembly of the nanoplatelets on dipped substrates, and the topological conversion of the hydroxide to the oxide by the heat treatment. The resultant NiCo2O4 thin films had structural features such as the crystallographic (111) orientation, the high specific surface area, and the high light-scattering ability. As a result, the NiCo2O4 thin films loaded with an N749 dye could work effectively as photocathodes in the configuration of dye-sensitized solar cells.
