Recently, we have developed a preparation process of GaN:ZnO by using Zn-Ga layered double hydroxide as a precursor and urea as a nitriding agent. In this study, we have attempted preparation of GaN:ZnO by using various nitriding agents, such as melamine and C3N4.

  21. Development of Novel Preparation Procedure of Metal Oxynitrides Using Solid Nitriding Agents, Y. Katakami, Y. Hayashi, K. Katagiri, K. Inumaru, The Ceramic Society of Japan The 31st Fall Meeting, 2018/09/05, Without Invitation, Japanese, The Ceramic Society of Japan, Nagoya Institute of Technology, etal oxynitrides are expected as novel functional materials, including photocatalysts and dielectric materials. Conventionally, metal oxynitrides are prepared under harmful NH3 flow at high temperatures. Therefore, development of a preparation procedure without using NH3 is desired. We have explored solid state compounds which can be utilized as nitriding agents. In this work, preparation of CaTaO2N by using calcium cyanamide is investigated in detail.
  22. Creation of Advanced Functional Materials Based on Inorganic Particles as Element-Blocks, Kiyofumi Katagiri, The Ceramic Society of Japan The 31st Fall Meeting, 2018/09/05, With Invitation, Japanese, The Ceramic Society of Japan, Nagoya Institute of Technology, Inorganic particles possess a number of features which are advantageous for applications in the various fields. In this study, novel inorganic particle-based hybrid materials have been employed as element-blocks for development of novel functional materials. We have firstly developed hybrids formed with lipid-coated photon upconverting nanoparticles (UCNPs) incorporating C70 fullerene. These nanohybrids were exploited as photosensitizers for photodynamic therapy by near infrared irradiation. Next, structural color coatings are prepared by an electrophoretic deposition (EPD) of SiO2 and carbon black (CB) particles. The arrangement of particle array is controlled by varying the deposition condition. The angular dependence of the structural color is drastically changed with the arrangement of particle array. In addition, robust structurally colored coating films with high abrasion resistance were prepared by the cathodic EPD method using monodispersed SiO2 particles, black substances and Mg2+ ions.
  23. Preparation of Structurally Colored Coating Films with High Abrasion Resistance via Cathodic Electrophoretic Deposition of Monodispersed SiO2 particles, R. Uesugi, K. Uemura, Y. Takeoka, K. Katagiri, K. Inumaru, Yukikazu Takeoka, 16th Meeting of the Japanese Sol-Gel Society, 2018/08/07, Without Invitation, Japanese, The Japanese Sol-Gel Society, Kansai University, Recently, we have developed the strategy for preparation of structurally colored coating films formed with array of SiO2 particles by the electrophoretic deposition (EPD) technique. However, the coating films have poor abrasion resistance. In this study, structurally colored coating films with excellent abrasion resistance were prepared by cathodic EPD method using monodispersed SiO2 particles, black substances and metal cations.
  24. Synthesis of Eu3+-doped Fluorescent Nanoparticles–Mesoporous Silica Composite and Elongation of Its Excitation Wavelength via Modification Using Organic Ligands, M. Kawashimo, K. Katagiri, K. Inumaru, 16th Meeting of the Japanese Sol-Gel Society, 2018/08/07, Without Invitation, Japanese, The Japanese Sol-Gel Society, Kansai University, LaF3:Eu3+ nanoparticles (NPs) were successfully prepared as fluorescent NPs via hydrothermal process. Composites formed with these NPs and mesoporous silica (MPS) were prepared to maintain high specific surface area of NPs. Fluorescent properties of composites, especially excitation wavelength, were investigated in detail. Modification of NPs in the composites by organic ligands enables emission of red fluorescence from the composites via near-UV excitation.
  25. Liquid Phase Synthesis of Zn-Ga Layered Double Hydroxide Nanocrystals and Its Conversion to GaN:ZnO Solid Solution, R. Yoshiyuki, Y. Hayashi, K. Katagiri, K. Inumaru, Y. Tokudome, Yasuaki Tokudome, 16th Meeting of The Japanese Sol-Gel Society, 2018/08/07, Without Invitation, Japanese, The Japanese Sol-Gel Society, Kansai University, In this study, we have demonstrated the facile preparation of Zn-Ga LDH nanocrystals as precursors for GaN:ZnO. We have investigated the reaction conditions including the quantities of reagents, and the reaction temperature to obtain the LDH with smaller crystallite size. Liquid phase synthesis of precursor LDH provides GaN:ZnO nanocrystals with uniformity in its atomic composition of Zn and Ga in each position of the samples.
