Tunable Multilayers of Self-Organized Silica Nanospheres by Spin Coating

Figure 3

Number of layers of self-organized NS as a function of the volume fraction and the acceleration. “1” indicates that a single layer was observed on the entire surface of the sample; “2” indicates that a double layer of organized NS was found on the whole sample surface. Noninteger numbers represent the proportion of double layers on these samples of NS of (a) 310 nm and (b) 540 nm diameter.
