We synthesized electrophoretic core-shell particles which we will use as the building blocks of optical structures, we used these particles to assemble photonic crystalline structures that interact strongly with visible light. The system reported here shows important features such as a fast, reversible, and tunable optical response to electric fields by changing the silica shell thickness and surface charge control agents.
