Abstract

We have shown a novel method for the synthesis of iron silicide nanoparticles on a water-soluble NaCl substrate using thermal layer-by-layer deposition of Fe–Si and post-annealing in ultra-high vacuum. The crystal structure, morphology and optical properties of highly dispersed Fe–Si-containing thin films have been studied. As a result, Fe₃Si nanoparticles were found to spontaneously form on the surface of salt with an excess of iron in a wide stoichiometric range. We propose a simple method to control the geometric shape of synthesized Fe–Si ferromagnetic nanoparticles by preparation of NaCl surface.

NaCl（001）表面硅化铁的纳米结构：自组装合成、形貌和光学性质

我们展示了一种在水溶性NaCl衬底上逐层热沉积Fe-Si并在超高真空中退火合成硅化铁纳米颗粒的新方法。研究了高分散含铁硅薄膜的晶体结构、形貌和光学性能。结果发现，Fe3Si纳米颗粒在盐的表面上自发形成，在一个很宽的化学计量范围内过量的铁。提出了一种通过制备NaCl表面来控制铁硅铁磁纳米颗粒几何形状的简单方法。
