High-Yield Synthesis of Silver Nanoparticles by Precipitation in a High-Aqueous Phase Content Reverse Microemulsion

Figure 4

TEM micrographs and their histograms for particles obtained in run-1 (a, c) and run-2 (b, d) from precipitation at 70^∘C in a reverse microemulsion containing 30 wt.% 0.5 M aqueous solution of AgNO₃ and 30 wt.% surfactant mixture. Insets show the corresponding high-resolution images of a silver particle.
