采用化学共沉淀和乳化相结合的方法合成了一种含有Fe 3 O 4-OA纳米粒子的油酸(OA)乳液,作为光子晶体的磁性结构单元。乳液滴的粒径分布在80- 110 nm之间,具有超顺磁性。通过该方法,实现了72%的磁性化合物Fe 3 O 4在乳液中的高负载分数。在外加磁场作用下,水中的乳液液滴可以很容易地自组装成光子晶体,并且通过移动磁体的位置可以在可见光谱范围内调谐阻带。高磁负载率乳液的合成方法将有助于可调光子晶体的制备和应用。
We report a simple approach to synthesize emulsion of oleic acid (OA) containing Fe3O4-OA nanoparticles as magnetic building block of photonic crystals by combined chemical co-precipitation and emulsification technology. The emulsion droplets exhibit dominant size distribution of 80–110nm and superparamagnetic behavior. A high loading fraction of magnetic compounds Fe3O4in emulsion of 72% was achieved by the approach. Upon application of a magnetic field, the emulsion droplets in water facilely self-assemble into photonic crystals, and the stop bands could be tuned in ranging visible spectrum by moving position of magnet. The method to synthesize emulsion with high magnetic loading fraction should facilitate preparation of tunable photonic crystals and expand their application.
