Fig. 7. (a) Low-resolution TEM image of Ag–Au alloy nanoplate. (b) HRTEM of a typical synthesized single Ag–Au alloy and (c) HRTEM image of a part of this alloy, which indicated the lattice plane constants of Ag (0.234 nm) and Au (0.232 nm). (d) EDS spectrum of (b) which shows the contribution of Ag and Au atoms in the Ag–Au alloy (x = 3.4 μmol).
