Diffracted intensity for the (200) peak of (a) the initial Ag–Au foil and dealloyed in 70% for (b) and (c) . Black line: raw data, red/green line: fit. The insets show the FESEM images.
Properties of nanoporous Ag–Au leaf as a function of dealloying time: (a) Ag composition, (b) ligament spacing from FESEM images (closed circle) and SAXS (open circles), (c) lattice parameter of regions and (closed and open circles, respectively) and of the final leaf (triangles) from XRD data and as predicted from EDS analysis (dashed line), and (d) amplitude of diffraction peak from region (closed circle) and region (open circles).The trend lines are given as guides to the eye.
Two- and three-dimensional representation morphologies for exposure times of (a) and (b) . The white is open space and the dark green is the remaining Au.
