Abstract：The elaborate combination of magnetically induced self-assembly and microfluidic techniques as well as the control of UV light time was demonstrated to prepare complex structural one-dimensional photonic crystal (PC) bowls in simple but powerful method through curing polymerizable emulsion droplet uncompletely. The structure and component of the as-obtained product were characterized by OM, SEM, TG-DSC and VSM.The results show that it presents a bowl-like geometric structure, and periodical chain-like structures composed of superparamagnetic Fe3O4@PVP nanoparticles are embedded in polymer matrix. The diameter, the thickness of the bottom and the color of the PC bowl can be controlled by the flow rate of oil phase, UV photo-polymerization time and the strength of the magnetic field. The effects of diameter and thickness of PC bowl on optical property were also investigated. Because of the unique geometric and optical structure, PC bowl are capable of self-display, optical switch and strong reflection intensity. These remarkable properties endow PC bowl with promising applications in energy saving display, optical switcher and anti-counterfeiting materials.
