Liquid Phase Deposition of Silica on the Hexagonally Close-Packed Monolayer of Silica Spheres
Figure 1
SEM images of silica spheres synthesized by the Stöber method. The average diameter of the silica spheres is 450 nm (a), 590 nm (b), and 810 nm (c), denoted by S-450, S-590, and S-810, respectively. The distribution of the diameters of silica spheres is shown in (d). Scale bars are 1 μm.
