| Outline of Final Research Achievements |
We aimed the development of fluorescence-enhanced thin film using gold- or silver-supported onto titanate nanosheets which had localized surface plasmon resonance. We studied the halide acid addition effects on supporting reaction. Addition of halide acid improved the efficient of supporting reaction using titanate nanosheets and metal oxide, but it was difficult to use for thin film. The other hand, we proposed the mechanism of metal supporting reaction between titanate nanosheets and metal oxide.
We found that the relation between the efficiency of supporting reaction and the concentration of titanate nanosheets and suspended amount of metal oxides.

液相合成チタン酸ナノシートは水分散性やシートの均一性が高い。本研究により，液相合成したチタン酸ナノシートに対する金属種の担持反応の機構を解明したことで，より多くの金属種の担持が行え，機能を付与したチタン酸ナノシートの開発が進展することが期待される。
また，チタン酸ナノシートで酸化金，酸化銀を還元することで，ナノサイズの金粒子，銀粒子を合成する新たな方法を示した。
