Abstract
Macrocrystalline colloidal assemblies with tunable non-spherical shape are fabricated through colloidal crystallization under an AC electric field. Al so, by field-induced drop breakup, uniform micrometer-sized macrocrystallin e particles can be synthesized (see Figure). Interestingly, the electrical field promotes infiltration of the suspending oil, which can be used for fa bricating photonic crystals with high refractive index mismatch.
