Monosized Core–Shell Fe3O4 (Fe)/Au Multifunctional Nanocrystals
We have synthesized highly crystalline, monosized Fe3O4(Fe)/Au magnetic-optic multifunctional nanocrystals using a modified polyol process. The formation of the core–shell structure was achieved in two consecutive steps, seeding the Fe3O4(Fe) core followed by coating the gold shell. The characterization demonstrates the core–shell nanostructure and provides particle size and distribution of the nanocrystals. The spectroscopic analysis gives three Fe oxidation states (Fe0, Fe+2 and Fe+3) in the core and the surface plasmon characteristic of the Au nanoshell, while the magnetic measurements show excellent susceptibility of the nanocrystals.
