Template Assisted Synthesis

Arrays of ZnO nanowires were synthesized within the well distributed pores of AAO template by employing an easy wet chemical method. Nanoporous AAO template was fabricated by electrochemical anodization of aluminium, controlling the anodization parameters. ZnO nanowires were characterized by SEM, XRD and EDS. It was found that the ZnO nanowires/AAO exhibits intense photoluminescence (PL) in the UV and visible regions. The blue emission band (432 nm) of the AAO template was originated from the singly ionized oxygen vacancies. The ZnO nanowires exhibit luminescence in the UV (379 nm) and in visible regions (460 and 510 nm), which can be attributed to the band to band electronic transition and oxygen vacancy related defect centers, respectively.

Highly ordered copper nanowire arrays were prepared by electrolytic deposition using porous anodic aluminum oxide (AAO) as template. The technique of removing the barrier layer of the AAO template by the pore widening procedure was investigated. The quality of the Au conducting layers sputtered at the bottom side of the AAO template was also studied. The direct current (DC) electrodeposition of copper nanowire arrays was performed efficiently above the Au layer inside the pores. The morphology of the copper nanowires was characterized by scanning electronic microscopy (SEM) and the composition of Cu nanowires was confirmed by energy dispersive X-Ray spectroscopy (EDS). The results showed that the best condition was found to be in phosphoric acid (6%wt) for 10 min to remove the barrier layer completely. Au layer was uniform and dense after sputtering for four times. Copper nanowire arrays were successfully prepared by three-electrode and two-electrode cell electro-deposition, but the nanowire arrays were more ordered by using three-electrode cell and the length of nanowires was more uniform. The diameter of a single Cu nanowire is less than 100 nm with the length up to around 10 μm, and the nanowires are well arranged in arrays.

AbstractNanostructured semiconductors have received a great deal of attention due to their unusual physical properties. The possibility of controlling these properties by varying the particle size, shape and surface properties is of great interest for nanoscale device applications in microelectronics, non-linear optics and optoelectronics in particular. Copper Indium diselenide (CIS), a p-type semiconductor with a band gap of about 1.04 eV has shown promise as an absorber for photovoltaic cells. Polycrystalline CIS film has been fabricated by various physical and chemical techniques over the past couple of decades. However, the preparation of nanostructured CIS is still challenging due to the fact that CIS tends to agglomerate resulting in large grains. Furthermore, an annealing step is also required to improve the film properties, which results in increased grain size. Here we report a simple, low cost solution to this problem through electrochemical deposition of CIS into the confined nanopores of an anodic aluminum oxide (AAO) template. The nanoporous aluminum oxide template, a few microns thick was prepared by either a one step or a two anodization in oxalic acidic media. CIS was deposited into the nanoporous AAO template by pulsed cathodic electro-deposition from an aqueous mixture. The electrodeposited nanowires had diameter ranging up to 40 nm and length ranging from 600 nm to 5 μm depending on the length of the template. The hybrid nanostructured CIS/AAO was annealed in vacuum at 230ºC for several hours to achieve stoichiometric CuInSe2 phase. The embedded CIS nanowires were characterized by X-ray diffraction and scanning electron microscopy. The optical bandgap was deduced from UV-Vis absorption spectroscopy measurements.
