Abstract: | Colloidal chemical synthesis of various types of magnetic nanocrystals is discussed with regard to recent discoveries.We first outline the chemical preparation of single-component magnetic nanocrystals with controlled size,shape,and uniformity based on several solution-phase methods,especially thermal decomposition and/or reduction method.Then we discuss the synthetic strategies of multi-component nanocrystals incorporating at least one magnetic component by manipulating heterogeneous nucleation and growth process.Toward the end,approaches for preparing hollow/porous magnetic nanocrystals are highlighted.We believe that the summarized chemical synthesis will pave the way for the future development of extraordinary magnetic nanocrystals. |
