| Research Abstract |
The liquid phase deposition (LPD) of metal oxide thin films at the liquid-liquid interface was investigated. Just after the start of the LPD reaction, depositions were observed continually at the liquid-liquid interface. The deposition grew two-dimensionally into a self-standing film with thickness of 1・m and domain size of up to ca. 1mm without any solid substrates. The self-standing film was formed with asymmetrical morphology, which consisted of flat surface on the side of the liquid-liquid interface and relatively rough surface on the side of the bulk solution. The structure was characterized by Raman spectroscopy, confirming that metastable ammonium titanium oxide fluoride (NH_4TiOF_3) was first deposited at the liquid-liquid interface, on which anatase-type titanium oxide (TiO_2) was deposited second to forming the asymmetrical bilayer structure.
