Here we present a simple but general method for constructing complex binary colloidal crystals with an almostfull range of size ratios, which is referred to as "template-assisted electric-field-induced assembly (TAEFIA)". Thedependence of the structures of binary colloidal crystals on size ratio (
) and volume fraction (
) of the colloidalsuspension was investigated. Binary colloidal crystals with ranges from 0.10 to 0.91 were fabricated, and an attemptto fabricate a triple colloidal crystal via TAEFIA was presented. We suggest that TAEFIA is a versatile way to growcolloidal crystals with binary or more complex structures.
