Fabrication of Oxide Nanohole Arrays and Their Applications

抄録

A variety of oxide nanohole arrays have been prepared from an aqueous solution process. An anodic alumina was immersed in a metal-fluoro complex solution at room temperature and a few hours immersion enabled us to obtain the nanohole arrays of oxides such as titania, iron oxide and tin oxide. The holes were about 200 nm in diameter and penetrated through the disk. Those nanohole arrays have a chance of controlling of the hole size and the thickness. The oxide nanohole arrays are attractive for a wide variety of application in different fields such as electrical, optical and chemical devices.
