Novel photoluminescence properties of magnetic Fe/ZnO composites: Self-assembled ZnO nanospikes on Fe nanoparticles fabricated by hydrothermal method
Magnetic Fe/ZnO composites showing the shape of "sea urchin" have been hydrothermally synthesized at 80 °C. The Fe nanoparticles are encapsulated inside a shell of self-assembled ZnO nanospikes. The Fe/ZnO composites display photoluminescence properties different from those of the ZnO entities generated similarly but in the absence of Fe powder: (i) a UV emission band is observed over the latter but not over the former, and (ii) the former shows an emission peak around 583 nm (wavelength) with intensity significantly stronger than that of the latter. Because of the encapsulation of the Fe nanoparticles, the Fe/ZnO composites are stable in air and high in magnetization. © 2009 American Chemical Society.
