Structural and Photoluminescence Studies of Porous Anodic Alumina Templates Prepared using Different Electrolytes
Abstract: The effect of different electrolytes on the structural and optical properties of porous anodic alumina (PAA) was investigated. PAA templates were synthesized using different electrolytes namely; oxalic, phosphoric, sulphuric and chromic acids maintained at two different temperatures, 18 and 27°C respectively. PAA templates were prepared using two-step anodization process in 0.3 M of sulphuric acid at 20 V, 0.3 M of oxalic acid at 40 V and 0.3 M of …

Synthesis of Metallic Copper Nanoflowers, Nanocrystals and Nanorods using Electrodeposition and Hydrothermal Techniques
Abstract: Copper nanoflowers and nanocrystals have been fabricated using two different techniques; electro-deposition of copper in polymer and anodic alumina templates (AAT) and Cetyltrimethyl-ammonium Bromide (CTAB)-assisted hydrothermal method. Nanorods of copper are produced by electrodeposition in 100 nm AAT. Scanning Electron Microscope (SEM) micrographs record some interesting morphologies of metallic copper nanoflowers and nanocrystals. Field Emission Scanning Electron Microscope (FESEM) has been used to determine morphology and chemical composition of polycrystalline …

Fabrication and Characterization of Copper Nanowires: An Overview
Abstract: Copper (Cu) is one of the most important metals in modern electronic technology. Keeping in view its role in nanoelectronics, we have fabricated copper nanowires of diameters 100 and 200 nm using Anodic Alumina and polymer membranes as templates. Template-based growth of copper nanowires has been realized using conventional electro deposition technique in an electrochemical cell designed in our laboratory. Fabrication of copper nanowires is one of the most important …

Structural and Optical Properties of Porous Anodic Alumina Annealed at Different Temperatures
Abstract: We report the structural and optical properties of porous anodic alumina (PAA) membranes synthesized using anodization technique, which were subsequently annealed at various temperatures up to 1000°C. The influence of annealing temperature on the structural aspects and photoluminescence (PL) properties of PAA was investigated. XRD analysis of the PAA confirmed the amorphous nature of the synthesized PAA membranes. The structural transition of the annealed templates from amorphous to ɣ-Al2O3 was …
