| Research Abstract |
In this study we developed new water-soluble compounds as precursors for photo-functional ceramics and synthesized high-performanced photoceramics using water as a processing solvent. We succeeded in development of new Si, Nb, and Ta water-soluble compounds through chemical complexation techniques. Our newly developed aqueous solution method using these compounds enabled us not only to prepare materials having properties superior to those for materials synthesized by the conventional method but also to provide highly morphologically controlled particles. Another important achievement in this study includes establishment of the new parallel synthetic scheme using water-soluble Si compound, which made possible to find quickly optimal compositions of high-brightness phosphors.
