Figure 1

TEM image and diffraction pattern of 4 ± 0.5 nm sized Au superlattice. a) TEM image showing the long range ordered Au nanocrystal. The FFT patterns of the SL and HRTEM image of representative nanostructure is inset in the Figure a where the single crystal nature is observed and most of the MPCs are in the same orientation. b) Selected area diffraction pattern for SL obtained using 20 cm camera length with several diffraction rings. The inset in Figure b represents the diffraction pattern obtained using 200 cm camera length revealing the overall crystalline structure of the SL to be hexagonally packed long range order. More examples are presented in SI (Figure S2). The FFT pattern inset in frame a and diffraction pattern inset in frame b are in good agreements and shows that the SL is long range ordered hexagonally packed.
