Fig. 7. Characterization of the final product of silver nanoparticles obtained by the 5% EG/2% PEG 100 binary polyol process at 80 °C for 120 min. (a)–(c) TEM micrographs at various magnifications. The boundaries of a penta-twinned silver nanoparticle were indicated using a red dot line. (d) EDS spectrum. (e) SAED pattern, revealing characteristic lattice spacings of metallic silver, which were indicated using a red solid line.
