A small amount of NaCl was added to each synthesis to prevent the aggregation of seeds. Varying concentrations of iron compounds were also added to the PVP solution to analyze their effect on the synthesis. The ethylene glycol used for every experiment contained trace amounts of chloride (3 μM) and iron (0.4 μM.). Magnetic stirring was applied throughout the entire synthesis. A set of samples were taken in the course of each synthesis using a glass pipet. To minimize temperature perturbations during sampling, the glass pipet was held just above the solution and preheated for 30 s before immersion. The samples were washed with acetone and then with water to remove most of the EG and PVP. During the washing process, the suspension was centrifuged at 16 000 rpm for 10 or 30 min (depending on whether acetone or water was used) to make sure that most of the silver particles taken from the reaction were recovered. Finally, the sample was dispersed in water for further characterization. For the scanning electron microscopy (SEM) and transmission electron microscopy (TEM) studies, a drop of the aqueous suspension of particles was placed on a piece of silicon wafer or a carbon-coated copper grid (Ted Pella, Redding, CA), respectively, and dried in the fume hood. After that, the sample was transferred to a gravity-fed flow cell and washed for 1 h with deionized water to remove the remaining PVP. Finally, the sample was dried and stored in a vacuum. SEM images were taken using a FEI field-emission microscope (Sirion XL) operated at an accelerating voltage of 20 kV. TEM and electron diffraction studies were performed with a Phillips 420 microscope operated at 120 kV.
