Al doped ZnO (AZO) nanostructures were produced by using an electrochemical process. The growth structures were then characterized structurally, optically, photoluminescence and Fourier transform infrared (FTIR) spectroscopy. The X-ray diffraction (XRD) studies assessed that AZO nanostructures has been successfully grown. The scanning electron microscope (SEM) image revealed the morphology with nearly uniform grains. The photoluminance (PL) spectrum shows that the ultraviolet emission band between 384 and 537 nm occurs the strong and broad green emission. The UV-vis has a strong absorption below 350 nm and performs transparent mode in the visible range. FTIR spectrum also attributes the transmittance light in visible range is higher than the near infrared range. It has been summarized that AZO nanostructure has been successfully grown by an electrochemical route.
