To address some of these uncertainties and to investigate the influence of the GNP size on the measured interparticle distances, we prepared 9DT films with 7.44 nm large GNPs and measured the interparticle distance using GISAXS, as described in the Supporting Information, Section S1.1. Larger particles have less curvature or rather larger facets. Thereby, the surface of the GNPs consists of a larger proportion of straight surfaces compared to edges.
