摘要：

A simple synthesis of core-shell nanoparticles (CSNPs) is reported using a modified polyol process. We found that it is possible to control the nucleation kinetics of nickel and copper salts in ethylene glycol by manipulating the boiling temperature of the solution. It is hypothesized that a 10 °C temperature difference is sufficient to separate out the nucleation of elemental copper and nickel nanoparticles. © 2010 American Chemical Society.
