Abstract

We describe the synthesis and properites of hybrid Fe₂O₃-Au nanoparticles synthesized using a wet chemical approach. These nanoparticles are compared with Fe₂O₃ and Au nanoparticles prepared in corresponding manners. We investigate the visible light photothermal properties of these different nanoparticles. It is found that the hybrid Fe₂O₃-Au nanoparticles are able to photothermally heat aqueous solutions as efficiently as pure Au nanoparticles, even with a significantly smaller concentration of Au. Importantly, the hybrid structures retain the properties of both materials, creating a multifunctional structure with excellent magnetic and plasmonic properties.
