This communication demonstrates the assembly of superparaferromagnetic colloidal nanoparticles into one-dimensional (1D) nanochain structures using an external magnetic field at room temperature, which were surrounded and linked by the amorphous carbon on the surface of nanoparticles. It is suggested that these nanochains have a fixed distance between adjacent colloidal particles and can diffract purple visible light (404 nm) under the induction of an external magnetic field.
本通讯展示了在室温下使用外磁场将超顺磁胶体纳米粒子组装成一维（1D）纳米链结构，这些纳米链结构由纳米粒子表面的非晶态碳包围和连接。研究表明，这些纳米链中相邻胶体粒子之间具有固定的距离，在外磁场的诱导下可以衍射出紫光（404nm）。
