In situ GISAXS characterization of a NP superlattice grown by macroscopic fast solvent evaporation and subsequent structural annealing via controlled nanoscale solvent adsorption. The initial NP solution contained a mixture of Au NPs of 6.5 nm and 2.8 nm core size in number ratio small/large = 60/40. The organization of the large NPs is predominant, as shown by correlation rods at qxy = 0.083 Å−1 and clearly discernible higher-order diffraction peaks. |
