1.SnO_2薄膜：采用Sn（II）离子氧化法在玻璃衬底上制备了透明SnO_2薄膜。对薄膜的基本性能进行了表征。用锑离子掺杂这些薄膜赋予薄膜导电性。2. MnO_2薄膜：利用Mn（II）离子氧化法在玻璃基片上制备了MnO_2薄膜。我们发现通过改变沉积条件，可以同时沉积存款Mn_3O_4和MnOOH薄膜。3.CeO_2薄膜：通过氧化Ce（III）离子在玻璃衬底上沉积CeO_2薄膜，具有阻隔紫外光的能力。该薄膜具有电致变色性和电催化活性。5. Fe_3O_4薄膜的制备：采用氧化Fe（II）离子的方法在玻璃衬底上制备了Fe_3O_4薄膜。这种方法可以使我们存款化学计量的铁氧体，如CoFe_2O_4，MnFe_2O_4等。

1.SnO_2 thin films : Transparent SnO_2 thin films were deposited on glass substrates by the oxidation of Sn(II) ion. The basic properties of the films were characterized. Doping of these films with antimony ion endowed the films with electrical conductivity. We also coated commercial TiO_2 powders with conductive SnO_2 thin films as an attempt to develop conductive fillers for polymers.2.MnO_2 thin films : MnO_2 thin films were deposited on glass substrates by the oxidation of Mn(II) ion. We found it possible to deposit Mn_3O_4 and MnOOH thin films as well by changing the deposition conditions.3.CeO_2 thin films : CeO_2 thin films, capable to cut-off ultraviolet light, were deposited on glass substrates by oxidizing Ce(III) ion.4.Co_3O_4 thin films : Co_3O_4 thin films were deposited on glass substrates by oxidizing Co(II) ion. The resultant thin films exhibited electrochromism and electrocatalytic activity for O_2 generation. The effects of the preparation condition on these properties were investigated.5.Fe_3O_4 thin films : Fe_3O_4 thin films were deposited on glass substrates by oxidizing Fe(II) ion. This method may enable us to deposit stoichiometric ferrites such as CoFe_2O_4, MnFe_2O_4, and so on.
