Gold (Au) nanostructures exhibit unique electronic, optoelectronic and plasmonic properties. This makes them potential candidates for applications in areas including biosensing, catalysis, optics, and electronics. These unique properties are governed by the precise control over their morphologies and size. The present work investigates the electrodeposition process of Au nanostructures. Additionally, the influence of applied potential, electrolyte pH and presence of L-cysteine on the morphology, size, distribution and density of Au nanostructured was studied. The observations elucidated the relationship between the process parameters and the formation mechanism of the Au nanostructures. The morphology and composition of these Au nanostructures were characterized by scanning electron microscopy and X-ray diffraction respectively.
