Metal and semiconductor nanomaterials exhibit highly tunable electric, magnetic, optical and catalytic properties. To obtain desired properties, structure and composition of the nanomaterials must be fine-tuned, which requires fundamental understanding of the growth mechanism. In the thesis research, we study Au-Cu alloy nanorods (NRs) growth mechanism using single particle scattering spectroscopy. From electrodynamics simulations, it was revealed that the unusual features of the single particle scattering spectra were due to atomic level structural defects made up of few atoms on the surface of NRs, caused by galvanic replacement reaction (GRR). NRs are further explored as templates for GRR using HAuCl4. Interestingly, NRs transformed into...
