Abstract: Hexagonal Porous Alumina (PA) nanostructures with ordered pores have been fabricated using two-step anodisation of aluminium. CdS nanowires of diameters between 50–60 and 100–110 nm have been grown on PA templates by two different chemical and electrochemical techniques. Microstructural properties of the nanowires have been investigated using Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). Selected area electron and X-ray diffraction patterns show the growth of polycrystalline nanowires with hexagonal CdS phase. Optical properties of CdS nanowires grown by two different methods have been studied using optical absorption, Photoluminescence (PL) and Raman spectroscopy.

Keywords: hexagonal porous alumina; polycrystalline nanowires; nanostructures; oxalic acid; CdS; cadmium sulfide; two-cell method; electrodeposition; aluminium anodisation; microstructure; nanotechnology; nanomanufacturing; optical properties.
