Abstracts Monodisperse sulfate Fe3O4@C core-shell nanoparticles are prepared by modified solvothermal method with potassium persulfate which are then dispersed in propylene carbonate. They are manipulated electrophoretically between transparent electrodes (ITO-coated glass). Depending on the strength of applied voltage, structural colors can be tuned precisely over visible range. Unlike to carboxylate Fe3O4@C particles, sulfate particles are not deposited irreversibly on the electrode during electrophoretic operation due to inert sulfate group on particle surface. Therefore, particle motion is reversible and stable under electric field and reflection color are highly reliable over hundreds of cyclic operations.
