 Abstract: The self-assembly of soft colloidal particles into three-dimensional ordered structures called artificial opals is promising approach for realization of photonic crystals. Self-assembly is simple, relatively fast and cost-effective. Despite its versatility, self-assembled opals often contain unintended internal defects like vacancies, domains and cracks. The occurrence of defects might not be so crucial for some applications such as sensors, catalyst, and adsorbent, but limit the applicability of artificial opals to be used as building block of optical devices. Colloidal particles in suspension possess surface charges that can be used to tune self-assembly process by applying external electric fields. The coupling between colloidal particles flow due to solvent evaporation and direct current (DC) electric fields may serve as a promising way to control the crystallization process. In this work we report the influences of an in-plane DC field on the formation and optical properties of the opal films made by using the capillary deposition method. The formation of opal films was followed using a camera and the optical properties were measured using UV-Vis spectrophotometry. We found that a low electric field can improve the crystallinity of opal films that is manifested in a high and sharp Bragg peak.
