Composite iron oxide-Zinc oxide (γ-Fe2O3/ZnO) was synthesized by two step method: in the first one step γ-Fe2O3 particles were obtained by a cetyltrimethylammonium hydroxide (CTAOH) assisted hydrothermal method at low temperature (60°C). In the second step, the γ-Fe2O3 particles were included in the ZnO particles synthesis, which were obtained by a hexamethylenetetramine (HMTA) assisted hydrothermal method at low temperature (90° C). SEM study of the samples revealed that the γ-Fe2O3/ZnO composites present a compact morphology. The γ-Fe2O3 and ZnO phases were identified by XRD, energy dispersive X-ray analysis (EDX) and analysis of the IR spectrum. The composite exhibit the characteristic emissions of ZnO under UV radiation and ferromagnetic behavior of γ-Fe2O3 under an external magnetic field.
