Abstract

original image

Binary colloidal crystals (see Figure) have been fabricated via the confined convective assembly method. By adjusting the ratio of the diameters of the small and large particles and the concentration of the small particles, various superlattices, including the previously reported LS2 and LS3 structures along with the new LS4 and LS5 structures, have been prepared.
