Facile and efficient ligand-directed asymmetric growth of Au–Ag bimetallic dimer nanostructures
A simple approach for the creation of anisotropic gold-silver dimer nanostructures (Au–Ag) with unique optical properties has been developed based on ligand adsorption on the gold surface (20 nm and 50 nm). Though a variety of gold-silver nanostructures have been designed and synthesized, it remains...

| 520 | |a A simple approach for the creation of anisotropic gold-silver dimer nanostructures (Au–Ag) with unique optical properties has been developed based on ligand adsorption on the gold surface (20 nm and 50 nm). Though a variety of gold-silver nanostructures have been designed and synthesized, it remains a major challenge to spacial control the site involved in nucleation and the overgrowth as a deposited metal for the construction of bimetallic nanostructures with specific orientations and unprecedented properties. Herein, we reported a simple and efficient method to synthesize Au–Ag bimetallic dimer nanostructures using a surface ligand 4-mercaptobenzoic acid (4-MBA). In addition, different ligands were investigated for creating the dimer nanostructures, and the possible mechanism for this process is provided. The highly polarization-dependent scattering spectra of the nanotructures were observed, and the Surface-Enhanced Raman Scattering (SERS) studies proved that these dimer nanostructures could be an excellent SERS-active nanosubstrate. We expect that this convenient strategy could be a generalized method for building noble-metal nanostructures.

Though a variety of gold-silver nanostructures have been designed and synthesized, it remains a major challenge to spacial control the site involved in nucleation and the overgrowth as a deposited metal for the construction of bimetallic nanostructures with specific orientations and unprecedented properties. Herein, we reported a simple and efficient method to synthesize Au–Ag bimetallic dimer nanostructures using a surface ligand 4-mercaptobenzoic acid (4-MBA). In addition, different ligands were investigated for creating the dimer nanostructures, and the possible mechanism for this process is provided. The highly polarization-dependent scattering spectra of the nanotructures were observed, and the Surface-Enhanced Raman Scattering (SERS) studies proved that these dimer nanostructures could be an excellent SERS-active nanosubstrate. We expect that this convenient strategy could be a generalized method for building noble-metal nanostructures.

Though a variety of gold-silver nanostructures have been designed and synthesized, it remains a major challenge to spacial control the site involved in nucleation and the overgrowth as a deposited metal for the construction of bimetallic nanostructures with specific orientations and unprecedented properties. Herein, we reported a simple and efficient method to synthesize Au–Ag bimetallic dimer nanostructures using a surface ligand 4-mercaptobenzoic acid (4-MBA). In addition, different ligands were investigated for creating the dimer nanostructures, and the possible mechanism for this process is provided. The highly polarization-dependent scattering spectra of the nanotructures were observed, and the Surface-Enhanced Raman Scattering (SERS) studies proved that these dimer nanostructures could be an excellent SERS-active nanosubstrate. We expect that this convenient strategy could be a generalized method for building noble-metal nanostructures.

Facile and efficient ligand-directed asymmetric growth of Au–Ag bimetallic dimer nanostructures |
| abstract |
A simple approach for the creation of anisotropic gold-silver dimer nanostructures (Au–Ag) with unique optical properties has been developed based on ligand adsorption on the gold surface (20 nm and 50 nm). Though a variety of gold-silver nanostructures have been designed and synthesized, it remains a major challenge to spacial control the site involved in nucleation and the overgrowth as a deposited metal for the construction of bimetallic nanostructures with specific orientations and unprecedented properties. Herein, we reported a simple and efficient method to synthesize Au–Ag bimetallic dimer nanostructures using a surface ligand 4-mercaptobenzoic acid (4-MBA). In addition, different ligands were investigated for creating the dimer nanostructures, and the possible mechanism for this process is provided. The highly polarization-dependent scattering spectra of the nanotructures were observed, and the Surface-Enhanced Raman Scattering (SERS) studies proved that these dimer nanostructures could be an excellent SERS-active nanosubstrate. We expect that this convenient strategy could be a generalized method for building noble-metal nanostructures.
