• Translation from original language as provided by authorSynthesis of nanoparticles is an important part of nanoscience and nanotechnology. This dissertation intended to explore laws governing nanoparticles' nucleation and growth, and to discover the relationship between crystal structures and morphology of nanoparticles through the preparation of magnetic metal nanoparticles, magnetic metal phosphides, and core-shell nanostructures between magnetic metals and noble metals using high-temperature organic solution method. The ultimate purpose of this study is to develop a universal strategy in the preparation of nanoparticles and core-shell nanostructures of magnetic metals and noble metals. First of all, two synthetic routes were used to prepare magnetic metal nanoparticles. In the first route, a strong binding ligand was used to control the growth of nanoparticles, whereas a heterogeneous nucleation process was introduced to adjust the monomer concentration in the nucleation and growth stages in the second rou
