Abstract

Zinc-doped superparamagnetic iron oxide nanocrystals (Zn-SPIONs) with enhanced saturation magnetization have been successfully synthesized using iron-oleate and zinc-oleate as precursors through facial hydrothermal approach. The synthetic procedure is new and more convenient compared with thermal decomposition method which requires expensive solvent, protective atmosphere and well-controlled heating rate.
