| Description | Journal: Chinese Physics B Monodisperse $Au–Fe_{3}O_{4}$ heterodimeric nanoparticles (NPs) were prepared by injecting precursors into a hot reaction solution. The size of Au and $Fe_{3}O_{4}$ particles can be controlled by changing the injection temperature. UV–Vis spectra show that the surface plasma resonance band of $Au–Fe_{3}O_{4}$ heterodimeric NPs was evidently red-shifted compared with the resonance band of Au NPs of similar size. The as-prepared heterodimeric $Au–Fe_{3}O_{4}$ NPs exhibited superparamagnetic properties at room temperature. The $Ag–Fe_{3}O_{4}$ heterodimeric NPs were also prepared by this synthetic method simply using $AgNO_{3}$ as precursor instead of $HAuCl_{4}$. It is indicated that the reported method can be readily extended to the synthesis of other noble metal conjugated heterodimeric NPs. |
