Abstract

We provide a preliminary study of ZnO nanostructure synthesis by coating aluminium and metallic plasmonic Au-Ag using seed mediated hydrothermal method. The growth process is carried out on the FTO substrate and characterized using UV-Vis, XRD, FESEM and EDX spectrophotometer system. The UV-Vis spectrum shows that strong absorption occurs at wavelengths around 370 nm, for all samples. The XRD pattern shows three diffraction peaks at angles 2θ = 34.43°, 36.32° and 47.49°. Each peak corresponds to the crystal fields of (100), (002) and (101). Morphology of the samples shows the presence of ZnO nanorod. A compact and denser nanostructure also obtained.
