摘要：
Maghemite (gamma-Fe2O3) nano-particles were produced by an innovative one-step method at room temperature and characterized using X-ray diffraction (XRD), Brunaure-Emmet-Teller analysis (BET), infrared spectrum (IR), scanning electron microscope (SEM), energy dispersive spectra (EDS), and photon correlation spectroscopy (PCS). The average particle size of the maghemite was estimated to be 45 and 57 nm, by SEM and PCS, respectively. The SEM image showed that the gamma-Fe2O3 nano-particles were of approximately spherical shape and a size below 50 nm. (C) 2010 Elsevier B.V. All rights reserved.
