摘要：

Heterostructured composites of ZnO/Fe3O4 and ZnO/Fe2O3 were respectively prepared by depositing magnetic nanoparticles on ZnO microrod templates through low-temperature hydrothermal procedures. The formation of the heterostructures was evidenced by high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), and Raman scattering analysis. Hexamethylenetetramine, a pH adjustor, was found to have important influence on the crystal phase of iron oxide in the heterostructured composites and greatly influenced the properties of the heterostructured composites. The heterostructured composites simultaneously possessed the magnetic properties of iron oxides and the optical properties of ZnO.
