ResumoSilver nanoparticles in 3D superlattices with heights and widths of several tens and hundreds of micrometers, respectively, have been fabricated, and the experimental parameters controlling their size and shape have been clearly identified. These parameters are the substrate temperature during the solvent evaporation, the initial concentration of the colloidal solution, and the deposition procedures. Scanning electron microscopy and small-angle X-ray diffraction are used to characterize the supracrystal phases.
