| dc.description.abstract | We report a study of the structure and electronic properties of a series of thiol-capped Au
nanoparticles (NP) of nominal sizes of 1.6, 2.4, and 4.0 nm. Transmission electron microscopy, x-ray
powder diffraction, x-ray absorption fine structure, and x-ray photoemission spectroscopy have been
used to investigate the size-dependent systematics of lattice contraction and charge redistribution
of these NPs. It is found that the lattice contracts and the d charge at the Au atom site depletes
relative to bulk Au as the size of the NP decreases. The implication of these observations is
discussed in terms of the interplay of quantum-size and surface effect. | en_US |
