摘要：
Bifunctional magnetic-optical ZnO-gamma-Fe2O3 hybrid nanomaterials have been synthesized via a layer-by-layer assembly technique on ZnO nanorod templates X-ray diffraction transmission electron microscope field emission scanning electron microscope high-resolution transmission electron microscope and X-ray photoelectron spectroscopy have been used to characterize the as-synthesized products The photoluminescence spectra indicate that ZnO-gamma-Fe2O3 hybrid nanomaterials exhibit enhanced UV emission and passivated defect emission The magnetic property investigation reveals that ZnO-gamma-Fe2O3 hybrid nanomaterials exhibit a superparamagnetic behavior (c) 2010 Elsevier B V All rights reserved
