Synthesis of High-Yield Gold Nanoplates: Fast Growth Assistant with Binary Surfactants

Figure 5

(a) TEM image of some Au nanoplates. (b) A typical TEM image of one hexagonal Au plate. The inset shows the corresponding SAED pattern taken by directing the electron beam perpendicular to the plate. The spots enclosed by squares could be indexed to the regular reflections {220} and {422}. The spots enclosed by circles could be indexed to the fractional reflections (1/3){422}. (c) HRTEM image of Au nanoplate. The measured plane spacing is 0.25 nm, three times the {422} lattice spacing.
