We present a synthetic protocol for the solution-phase synthesis of monocrystalline, metallic iron nanoparticles based on seed-mediated growth, showing near-single nanometre control over particle size. A shape evolution to cubic nanoparticles is also observed with increasing size. Magnetic properties were measured after surface oxidation, showing the potential of our protocol to tune the magnetism of iron nanoparticles for applications requiring superparamagnetic or ferromagnetic nanoparticles.
我们展示了一种基于种子介导生长的用于溶液相合成单晶金属铁纳米颗粒的合成方案，该方案能实现对颗粒尺寸近乎单纳米级别的控制。随着尺寸增加，还观察到向立方纳米颗粒的形状演变。在表面氧化后测量了磁性，这表明我们的方案在调整铁纳米颗粒磁性以满足需要超顺磁性或铁磁性纳米颗粒的应用方面具有潜力。
