Morphological evolution of Ag nanoparticles to Au3Ag nanoframes. a Scanning electron microscopy (SEM) and b transmission electron microscopy (TEM) overview of Au3Ag NFs showing high structural uniformity. The schematic diagram, SEM, TEM, and energy-dispersive X-ray (EDX) mapping images of c Ag NPs collected at the 36th min before HAuCl4 addition, d AuAg12 NPs collected at the 38th min after HAuCl4 addition, e Au2Ag NCs collected at the 42th min, and f Au3Ag NFs collected at the 46th min
