“…The Power-law relationship (D) between the Q R and the core and ligand shell mass of the nanoclusters was calculated using the ScÅtter software. [57][58][59] The differences of the exponent coefficient originates from different contrast conditions. The exponent for the gold core was calculated from SAXS data while for the case of ligand shell, it was determined from contrast matching SANS data.…”

Quantifying the Solution Structure of Metal Nanoclusters Using Small‐Angle Neutron Scattering

et al. 2022

Metal nanoclusters are a unique class of synthetic material, as their crystal structures can be resolved using X-ray diffraction, and their chemical formula can be precisely determinated from mass spectroscopy. However, a complete structure characterization by these two techniques is often a challenging task. Here, we utilize small-angle neutron scattering (SANS) to directly quantify the key structure parameters of a series of silver and gold nanoclusters in solution. The results not only correlate well to their crystallographic structures, but also allow the quantification of the counterions layer surrounding charged nanoclusters in solution. Furthermore, when combining with X-ray scattering, it is possible to estimate the molecular weight of both the metal core and the ligand shell of nanoclusters. This work offers an alternative characterization tool for nanoclusters without the requirement of crystallization or gas phase ionization.
