Figure 6
PDFs of silver nanoparticles of diameter ∼11 nm. (a) Complete fitted region and (b) low r-value. Experimental (circle) and refined (continuous red line) PDF are shown. Below the curve are presented the difference (continuous green line), the mean value (solid black line) and the standard deviation (dashed line) of the difference. G(r) is shown scaled by the factor refined in PDF analysis. In (b) the vertical lines show the different peaks associated with the Ag–Ag distances; the additional oscillations correspond to mathematical artifacts from the Fourier transform. |
