abstract = {We report on a time-resolved study of the colloidal
nanoparticle self-assembly into a high-quality nanoparticle
crystal with the face-centered cubic crystallographic
symmetry. In particular, the grazing-incidence small-angle
X-ray scattering technique was employed to track kinetics of
the solvent evaporation driven self-assembly on casting a
drop of plasmonic Ag nanoparticles on a silicon substrate.
The short-range (cumulative) disorder typical for
paracrystal structures before the complete solvent
evaporation at 300–350 s from the drop casting was found
with the exception of the time window of 125–150 s where a
highly regular transient phase with the long-range order was
observed. This temporary improvement of the nanoparticle
crystal perfection occurring shortly before the complete
solvent evaporation is the main message of the paper. It is
attributed to interaction between the surfactant shells of
the neighboring nanoparticles getting into contact in the
presence of solvent residua to the end of the solvent
evaporation which results in a larger nanoparticle
hydrodynamic diameter with a smaller dispersion and
improvement of the crystallization. This process has direct
impact on the quality of the resulting nanoparticle crystal
and tailoring its properties.},
