  • Synthesis of hollow and aggregated CeO <inf>2</inf> :Sm <sup>3+</sup> microspheres and their redox-responsive luminescence

    Umehara T., Hagiwara M., Fujihara S.

    Journal of Alloys and Compounds (Journal of Alloys and Compounds)     1074 - 1081 2019.05

    ISSN  09258388

     View Summary

    © 2019 Elsevier B.V. Hollow and aggregated microspheres of an Sm 3+ -doped CeO 2 phosphor material were synthesized by liquid processes using organic materials as a template and a structure-directing agent, respectively The microstructure of both the microspheres obtained were characterized as their crystallite size and specific surface area because they were comprised of CeO 2 :Sm 3+ nanocrystals approximately 20 nm in size. The microspheres showed orange luminescence due to electronic transitions of the Sm 3+ ions upon excitation with ultraviolet light. The luminescence intensity was decreased when the microspheres were treated with an aqueous L(+)-ascorbic acid solution as a reductant. The intensity was then recovered by treating the microspheres with an H 2 O 2 solution as an oxidant. Such the redox-responsive luminescence switching is promising for sensing applications if the sensitivity can be controlled well. The relationship between the structural features of the microspheres and the luminescence switching property was then examined in detail.

  • Synthesis of Ca–Co hydroxides and their use in facile fabrication of textured Ca<inf>y</inf>CoO<inf>2</inf> thermoelectric ceramics

    Shimonishi R., Hagiwara M., Fujihara S.

    Ceramics International (Ceramics International)  45 ( 3 ) 3600 - 3607 2019.02

    ISSN  02728842

     View Summary

    © 2018 Elsevier Ltd and Techna Group S.r.l. A brucite-type hydroxide of CazCo1−z(OH)2 with a high Ca content was synthesized and utilized as a single-source precursor for the fabrication of bulk ceramics of a semiconducting layered calcium cobaltite CayCoO2. Plate-like CazCo1−z(OH)2 particles with z up to 0.22 were reproducibly obtained by a reverse co-precipitation method using KOH as an alkaline source. Uniaxial pressing of the plate-like CazCo1−z(OH)2 particles (z = 0.22), which was calcined at 373 K beforehand, at a pressure as high as 500 MPa produced a highly dense green pellet where the plate-like particles were stacked along the pressing direction. The green pellet was then converted by a heat treatment at 923 K into an oxide ceramic of preferentially (010)-oriented CayCoO2 via a topotactic-like pyrolytic reaction maintaining edge-sharing CoO6 octahedra. Although the ceramic also contained a minor insulating Co3O4 phase (16.7 ± 0.7 mol% estimated from thermal analysis), the electrical measurements proved its p-type semiconducting behavior resulting from the CayCoO2 phase with enhanced Seebeck coefficient exceeding 160 μV/K at room temperature.

  • Structural improvement of ZnO electrodes through solution-processed routes for enhancing open-circuit voltage in dye-sensitized solar cells

    Tanaka E., Nurdiwijayanto L., Hagiwara M., Fujihara S.

    Journal of Solid State Electrochemistry (Journal of Solid State Electrochemistry)  22 ( 10 ) 3119 - 3127 2018.10

    ISSN  14328488

     View Summary

    © 2018, Springer-Verlag GmbH Germany, part of Springer Nature. We report herein one of our recent studies on nanostructured ZnO electrodes for application in dye-sensitized solar cells, focusing on achieving a higher open-circuit voltage (VOC). ZnO films were obtained through solution-processed routes including pyrolytic conversion of layered hydroxide zinc acetate (LHZA) films deposited on a fluorine-doped tin oxide-coated conducting glass substrate by a chemical bath deposition method. The morphology of the initial LHZA and the converted ZnO films was tuned from a thick (approximately 12 μm) flower bed-/lawn-like bilayer structure to a thin (1.2 μm) lawn-like quasi-monolayer structure by decreasing the Zn source concentration in the chemical bath. VOC was found to be enhanced with this morphological change from 0.692 (the bilayer structure) to 0.735 V (the quasi-monolayer structure). Fine tuning of the quasi-monolayer structure by introducing the grain growth effect led to VOC of the cell as high as 0.807 V, although a short-circuit photocurrent density (JSC) remained low. Further attempts were then made to increase JSC while maintaining the high VOC. When the thickness of the lawn-like monolayer film was increased up to approximately 5 μm, the resultant cell showed VOC = 0.750 V, JSC = 6.20 mA cm−2 and a conversion efficiency (η) of 2.83%. The film with a modified flower bed-/lawn-like bilayer structure approximately 11 μm in thickness finally yielded VOC = 0.741 V, JSC = 13.6 mA cm−2, and η = 5.44%.

  • Sol-gel processing of fluoride and oxyfluoride materials

    Fujihara S.

    Handbook of Sol-Gel Science and Technology: Processing, Characterization and Applications (Handbook of Sol-Gel Science and Technology: Processing, Characterization and Applications)     333 - 359 2018.07

    ISSN  9783319320991

     View Summary

    © Springer International Publishing AG, part of Springer Nature 2018. 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.

  • A novel synthesis method of delafossite-type CuYO<inf>2</inf> using a layered yttrium hydroxide as an yttrium source

    Narushima S., Shimonishi R., Hagiwara M., Fujihara S.

    Journal of the Ceramic Society of Japan (Journal of the Ceramic Society of Japan)  126 ( 5 ) 286 - 291 2018.05

    ISSN  18820743

     View Summary

    © 2018 The Ceramic Society of Japan. All rights reserved. A facile synthesis method of delafossite-type CuYO2 using a layered yttrium hydroxide (LYH) was developed. LYH microplates and Cu2O nanoparticles were both prepared from aqueous solutions and used as raw materials for the solid-state reaction to form CuYO2. It was found that CuYO2 could be obtained by heating LYHCu2O mixed powder at 900°C for 4 h under a N2 atmosphere. Although the product contained a slight amount of Y2O3, the heating time used in the proposed method was much shorter than that required for the conventional synthesis method via the Cu2Y2O5 precursor phase. Analysis of the X-ray diffraction pattern showed that the CuYO2 powder synthesized using LYH contained the 3R-type polymorph as the major content, whereas a larger content of the 2H-type polymorph was included in the powder synthesized by the conventional method. Based on these results, a topotactic reaction maintaining the layered structure of LYH was proposed as the formation mechanism for CuYO2 in LYHCu2O mixed powder.
