制备方法与用途

制备方法

将按反应摩尔比计算量的六氟乙酰丙酮铵的乙醚溶液与氯化钇的水溶液混合并搅拌。得到的六氟乙酰丙酮钇螯合物进入乙醚层中。随后，乙醚溶液用无水硫酸钠干燥后蒸去乙醚，得到粗产品。可用水-甲醇（9∶1）混合溶剂重结晶纯化，所得纯品很可能是六氟乙酰丙酮钇的二水合物。若将上述产品在五氧化二磷存在下，于室温及3Pa压力下干燥72小时，即可得到无水的六氟乙酰丙酮钇。

  氧等离子体辅助化学气相沉积氧化钇在硅上的化学、物理和电学特性

  摘要：

  了解和控制化学气相沉积高 k 电介质的界面和整体化学稳定性是一个重要的研究问题。我们报告了使用两种二酮酸钇前体通过氧等离子体辅助化学气相沉积沉积的 Y 2 O 3 薄膜。电容-电压数据中出现不可接受的大滞后，可能是由于掺入了氟。观察到来自含 F 前体的薄膜。对于用氢化前体沉积并在沉积后暴露在空气中的薄膜，透射电子显微镜显示退火后的三层结构，电子能量损失光谱和 X 射线光电子能谱显示薄膜在顶部是化学计量的 Y 2 O 3 和钇硅酸盐/SiO 2 在电介质/Si界面。傅里叶变换红外光谱、X 射线衍射和原子力显微镜也证实了这种结构。在介电沉积之前对硅表面进行预氮化会阻碍与衬底的反应。促进Y 2 O 3 结构。精心设计的蚀刻实验直接证明了硅基板的大量消耗。讨论了与观察到的结果一致的可能机制，包括 Si 扩散、Y 2 O 3 的结晶以及与吸收的 OH 反应。

  摘要：

  摘要 Sc(III)、Y(III)、Th(IV)、U(IV) 的各种β-二酮螯合物。U(VI)、Zr(IV) 和镧系元素已经过制备、表征和研究，以确定它们是否具有挥发性和稳定性。采用的配体是乙酰丙酮 (AA)、三氟乙酰丙酮 (TFAA)、六氟乙酰丙酮 (HFAA) 和二戊酰甲烷 (DPM)。螯合物在分级真空升华器中升华，并记录各个螯合物的重结晶温度区。镧系元素乙酰丙酮化物均不具有挥发性，但 Sc(III)、Th(IV)、U(IV) 和二氧铀 (VI) 乙酰丙酮化物是热稳定的，并且在 1 毫米汞柱压力下低于 150° 时非常易挥发。镧系元素、Sc(III)、Y(III) 和二氧铀 (VI) 三氟乙酰丙酮化物是挥发性的，可以在 150°以下真空升华，但热不稳定；只有 Th(IV) 螯合物足够稳定，可以通过升华定量回收。Sc(III)、Y(III)、Th(IV) 和镧系元素六氟乙酰丙酮化物是热稳定的，在真空或大气压下，温度低于
