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.

研究了在液-液界面液相沉积金属氧化物薄膜。在LPD反应刚开始后，在液-液界面处连续观察到沉积。沉积层呈二维生长，形成厚度约为1 μ m的自支撑薄膜，畴尺寸约为100 nm。1 mm，无任何固体基质。形成的自支撑膜具有不对称的形貌，其由在液-液界面侧的平坦表面和在本体溶液侧的相对粗糙的表面组成。通过拉曼光谱表征了该结构，证实了在液-液界面首先沉积了亚稳态的氟化钛铵（NH_4TiOF_3），然后在其上沉积了锐钛矿型的二氧化钛（TiO_2），形成了不对称的双层结构。
