摘　　要：多孔氧化铝(PAA)以其支持均匀有序的纳米级微孔、自身可被大面积制备和在450 nm左右的蓝光发射等特性,成为纳米级材料理想的宿主.通过自组织作用形成的多孔氧化铝具有纳米级的孔径、并且具有尺寸可调等很多优点,因此在制备纳米量级的纤维、纳米棒、金属管、半导体等新型材料上,多孔氧化铝已经成为一种常用的模板.本文通过电子束蒸发在硅衬底镀一层铝膜,然后在酸性电解质溶液中阳极氧化制得多孔氧化铝模板,采用X射线衍射(XRD),电子扫描显微镜(SEM)和光致发光谱(PL)对其结构、表面形貌和性能进行了分析.Porous alumina （PAA） since its support of orderly uniform nano-porous, can be prepared and a large area around 450 nm B1u-ray emission properties, it has become an ideal host of nanoscale materials. The role of self-organized through the formation of nano-porous alumina with pore size, and has many advantages, such as adjustable-size, order of magnitude in the preparation of nano-fibers, nano-rods, metal tubes, and other new types of semiconductor materials, the porous alumina as a commonly used templates. Plating a aluminium layer in silicon substrate through the electron beam evaporation, and then obtain the porous alumina template through anodie oxidation in the electrolyte solution of acidity. The samples were characterized by X-ray diffraetion（XRD）, electronic scanning microscope （SEM）, and photoluminescence（PL）.
