合成了由单分散超顺磁性胶体粒子组成的光子晶体。颗粒（见图）是通过苯乙烯在新沉淀的表面改性的氧化铁纳米颗粒存在下的乳液聚合获得的。磁场使粒子自组装，并控制阵列的衍射波长和晶体参数。
Photonic crystals consisting of monodisperse superparamagnetic colloidal particles have been synthesized. The particles (see Figure) are obtained by emulsion polymerization of styrene in the presence of freshly precipitated surface-modified iron oxide nanoparticles. A magnetic field self-assembles the particles and controls the diffraction wavelength and crystal parameters of the array.
