aExperimental and calculated X-ray diffraction patterns of the hybrid (1). The single contributions of the cuboctahedral, icosahedral, and decahedral clusters with the relative population (mass fraction), size distribution, and size-dependent strain are also shown. For comparison the (hkl) Bragg peaks of the “bulk” Au are also indicated. The size and strain distribution of the cuboctahedral (C), icosahedral (I), and decahedral (D) structure type as obtained from the analysis and simulation of the X-ray patternaare shown inb,c, andd, respectively. The population of the “ideal” cuboctahedron (C) is about 2/3 demonstrating the very high structural quality of the synthesized Au nanocrystals. The average cluster size for all the structure types is about 2 nm
