- Resumen
This thesis discusses the fabrication and characterization of self-ordered porous alumina structures. Two anodizing techniques 'two step anodization' and 'hard anodization' were used to prepare porous alumina structures. The physical properties of several porous alumina structures were studied using various characterization techniques: namely, X-ray diffraction, optical spectroscopy in the visible-ultraviolet (UV-Vis) and infrared range (FT-IR), photoluminescence spectroscopy (PL), nanoindentation and friction measurements. Derived applications such as metal nanowire arrays and polymer nanopillar arrays were prepared using porous alumina templates. The preliminary results from the novel and promising anodization approach of discontinuous anodization showed that the pore diameter in porous alumina could be modulated. A three-dimensional porous alumina structure makes novel applications possible in the fields of nanostructured materials and optical nanodevices.
