摘要
A facile chemical approach to producing monodisperse Fe3O4 nanoparticles is developed in the presence of oleic acid and laurylamine solution. These particles capped with organic ligands could be readily dispersed in nonpolar hexane. Transmission electron microscopy observations indicated that the as-synthesized nanoparticles were single crystals. The solvethermal temperature and consequent aging time are demonstrated to be critical for size distribution.
