Colloidal crystals with a diamond and pyrochlore structure display wide photonic band gaps at low refractive index contrasts. However, these low-coordinated and open structures are notoriously difficult to self-assemble from colloids interacting with simple pair interactions. To circumvent these problems, one can self-assemble both structures in a closely packed MgCu<sub>2</sub> Laves phase from a binary mixture of colloidal spheres and then selectively remove one of the sublattices. Although La ...[more]
