Nanoporous Ag-Au Bimetallic Triangular Nanoprisms Synthesized by Galvanic Replacement for Plasmonic Applications

Figure 2

Atomic percentage profile of Ag-Au TNPs calculated from the relative counts in the EDS line scan, as indicated by the red line in the scanning transmission electron microscopy (STEM) image in the inset. The inset shows the morphology of Ag-Au TNPs imaged by STEM, Ag element, and Au element, respectively.
