Template assisted synthesis of SnO_2 nanorods by immerse and filtration technique, vacuum and drop setting

摘要

Honeycomb-shaped and ordered arrays of nano-pore AAO template with a uniform pores size was produced utilizing a two-step an anodization process. Highly ordered SnO_2 nanorods arrays have been selectively fabricated via a convenient (immerse and filtration) technique and (vacuum and drop) setting using anodic aluminum oxide (AAO) as a hard template. The morphology of the samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (FESEM), and Energy-dispersive X-ray spec-troscopy (EDX) techniques. The optical characterizations were examined by UV-VIS and Photoluminescence (PL). Scanning microscopy images indicate that the SnO_2 nanorods are relatively uniform with the outer diameter matching well with the pore diameter. XRD and EDX indicated that these polycrystalline SnO_2 nanostructures with well-defined composition were obtained.
