“…This is because the rapid interdiffusion of Ag and Au atoms necessary for the formation of homogeneous alloy nanoparticles was facilitated by the Fig. 1 Colloidal solutions of Ag, Au, and Ag-Au bimetallic nanoparticles combination of reduced dimension of the Ag nanoparticles, elevated temperatures, and the large number of vacancy defects created by the replacement reaction [38][39][40][41][42]. The composition of the alloy nanoparticles was determined by the Ag-to-HAuCl 4 ratio used in the preparation and the size of the starting Ag nanoparticles.…”

Solutions of Ag and Au nanoparticles are strongly colored because of localized surface plasmon resonance in the UV/visible spectral region. The optical properties of these nanoparticles may be tuned to suit the needs of the application. This article summarizes our work in recent years on the solution synthesis of nanoparticles with tunable optical properties. The systems of interest include zero-dimensional bimetallic Ag-Au nanoparticles with different structures, one-, two-, and three-dimensional anisotropic monometallic Ag or Au nanoparticles. All of these nanosystems were prepared from colloidal synthesis through simple changes in the synthesis conditions. This is a demonstration of the versatility of colloidal synthesis as a convenient scalable technique for tuning the properties of metallic nanoparticles.

“…where D is the interdiffusion coeffi cient; C is the atomic concentration of metal A as a function of time ( t ) and distance ( x ) from the A -B interface; and C s is initial concentration of metal A at the A-B interface ( x = 0), which is in direct proportion to the number of A atoms deposited on metal B ; D is strongly dependent on temperature and the energy barrier to diffusion, [ 76,78 ] and can be described by the Arrhenius equation:…”

This article provides a progress report on the use of galvanic replacement for generating complex hollow nanostructures with tunable and well-controlled properties. We begin with a brief account of the mechanistic understanding of galvanic replacement, specifically focused on its ability to engineer the properties of metal nanostructures in terms of size, composition, structure, shape, and morphology. We then discuss a number of important concepts involved in galvanic replacement, including the facet selectivity involved in the dissolution and deposition of metals, the impacts of alloying and dealloying on the structure and morphology of the final products, and methods for promoting or preventing a galvanic replacement reaction. We also illustrate how the capability of galvanic replacement can be enhanced to fabricate nanomaterials with complex structures and/or compositions by coupling with other processes such as co-reduction and the Kirkendall effect. Finally, we highlight the use of such novel metal nanostructures fabricated via galvanic replacement for applications ranging from catalysis to plasmonics and biomedical research, and conclude with remarks on prospective future directions.

The decay of X-ray satellite intensities is used to measure interdiffusion in amorphous Ni 55 Zr 45 multilayers as a function of repeat distance, time and temperature. The data are compared to analytical expressions and a numerical simulation based on the analysis of Stephenson for stress effects. It is concluded that stress effects are very strong and that the analysis fits them quantitatively in a system such as a-Ni-Zr with marked diffusional asymmetry.
