以乙酸锌为起始试剂，采用溶胶-凝胶法制备了氧化锌薄膜。所用的前体用乙醇胺和/或α-羟基酮及其衍生物改性。用单乙醇胺改性的溶胶和用单乙醇胺和乙偶姻共改性的溶胶得到c轴垂直于基底的取向膜。共改性的试样表现出更高程度的取向。用单乙醇胺改性的溶胶在400°C的低温下结晶，并具有不寻常的褶皱结构。丙酮醇和肼的共改性也适用于溶胶-凝胶氧化锌薄膜。在热分析的基础上，讨论了单乙醇胺改性溶胶制备的薄膜的c轴取向和褶皱结构。
Zinc oxide thin films were fabricated via a sol-gel method using zinc acetate as a starting reagent. The precursors used were modified with ethanolamines and/or α-hydroxyketones, and their derivatives. Oriented films with the c-axis perpendicular to the substrate were obtained from the sols modified with monoethanolamine and co-modified with monoethanolamine and acetoin. The co-modified specimens exhibited higher degrees of orientation. The film from the sol modified with monoethanolamine crystallized at the low temperature of 400°C and had an unusual plicated structure. The co-modification with acetol and hydrazine was also applicable to the sol-gel zinc oxide film. The c-axis orientation and the plicated structure of the films from the sol modified with monoethanolamine were discussed on the basis of the thermal analysis.
