| 摘 要： | 利用LB膜技术发展了一种制备组分可控的超薄陶瓷膜的方法。以Ce,Y的β－二酮络合物作为表面离子，替代传统的亚相离子，制得混合LB膜。并将它作为前驱物成功制得了Y2O3掺杂的CeO2(YDC)超薄膜。XPS谱表明，膜中Ce与Y的含量比控制得很好。

| Abstract: | A fabrication technique of component-controllable multi-component ultrathin ceramic films has been developed by a promising LB method. The precursor of Y2O3-doped CeO2 (YDC) ultrathin film was prepared with cerium IV 2,2,6,6-tetramethyl-heptanedionate (Ce(tmhd)4) and yttrium 2,2,6,6-tetramethylheptanedionate (Y(tmRd)3) as "surface ions" on subphase surface instead of traditional "subphase ions". The YDC film was successfully fabricated after ultraviolet/ozone treatment and annealing in oxygen ambience with the precursor. XPS results proved that the surface of the fired film contained mainly Ce, O and Y and that the elemental ratio of Y/Ce was well controlled. |
