Silver nanoparticles were sputter deposited through self organized hexagonally ordered porous anodic alumina templates that were fabricated using a two-step anodization process. The average pore diameter of the template was 90 nm and the interpore spacing was 120 nm. Atomic force microscope studies of the sputter-deposited silver nanoparticle array on a Si substrate indicate an approximate replication of the porous anodic alumina mask. The nature of the deposition depends strongly on the process parameters such as sputtering voltage, ambient pressure and substrate temperature. We report a detailed study of the sputtering conditions that lead to an optimal deposition through the template.

In this study, oxide dissolution treatment was used for the formation of well ordered porous anodic alumina. Porous anodic alumina was formed on mechanically polished high purity aluminium by anodizing at 50 V in 0.3 M oxalic acid of 15°C for 60 minutes. It is observed that the pore arrangement of as anodized porous anodic alumina was randomly distributed and showed no ordered hexagonal cell structure. As anodized porous anodic alumina were then subjected to oxide dissolution treatment of increasing exposure duration, up to three minutes. Micrographs were captured by using scanning electron microscope. Pore arrangement of porous anodic alumina subjected to oxide dissolution treatment up to two minutes were similar to one another where no ordered periodic structures were formed. .When porous anodic alumina subjected to oxide dissolution treatment for three minutes, a perfect hexagonal pore arrangement was obtained.

The influence of manganese content on the formation of well-ordered porous anodic alumina was studied. Porous anodic alumina has been produced on aluminium substrate of different manganese content by single-step anodizing at 50 V in 0.3 M oxalic acid at 15°C for 60 minutes. The well-ordered pore and cell structure was revealed by subjecting the porous anodic alumina to oxide dissolution treatment in a mixture of chromic acid and phosphoric acid. It was found that the manganese content above 1 wt% impaired the regularity of the cell and pore structure significantly, which can be attributed to the presence of secondary phases in the starting material with manganese content above 1 wt%. The pore diameter and interpore distance decreased with the addition of manganese into the substrates. The time variation of current density and the thickness of porous anodic alumina also decreased as a function of the manganese content in the substrates.
