Anodic aluminum oxide(AAO) template has a highly ordered nanoporous arrays with adjustable and controllable pore diameter ranging from 5 nm to 200 nm.AAO template formed by different method has different effort and use.The AAO template used in this article was formed by anodizing aluminum in the oxalic acid of 0.3 mol/L at 40 V and through two-step anodizing oxide method.The AAO template was used to synthesize ZnS nanowire arrays by the method of electrochemical deposition.The production can be proved to be ZnS nanowire arrays by transmission electron microscope electron diffraction image and energy dispersive X-ray spectrum.The TEM image shows that the diameter and length of the ZnS nanowires are about 50 nm and 20 μm

respectively.The photoluminescence spectrum has a great contrast before and after having assembled ZnS nanowires.The photoluminescence spectrum display that the AAO template with ZnS nanowire arrays has two more emission peaks at 409 nm and 430 nm

and they are more intensive under the excitation with longer wavelength.There are different characters comparing with nanoparticles

nanorods and nanowires synthesized by other different methods.One is that the peak intensities are more strong if excitation wavelengths are more longer;the other is that the bandwidth is more narrow.To explain the origin of the ZnS nanowire arrays emission spectrum

the main reason is the transition caused from conduction band to accepter energy rank and from almsgiver energy rank to acceptor energy rank;the two types of luminescence act together so that ZnS nanowire arrays have two close emission peaks;perhaps the other reason is the embellishment of ethanol.Else

the reason of narrow bandwidth is ZnS nanowire arrays have the uniform size distribution.
