摘要： 采用模板法制备了花球形和叶片形Y2O3材料。X射线衍射表明这种材料为立方晶系Y2O3。采用扫描电镜对其表面形貌进行了表征，证实其叶片具有微米级的长度和纳米级的厚度。表面浸润性研究表明花球形材料具有超亲水性质，叶片形材料具有超疏水性质。

Abstract: Regular polyvinyl alcohol arrays were prepared by a template method. This regular arrays show a special optical result. A character 'E' was replicated from microscopy by using these arrays.
