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Y2 O3 掺杂的CeO2 (YDC)超薄膜。XPS谱表明 。
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-tetramethylheptanedionate (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.
