The α-Fe2O3 were prepared by hydrothermal method,in which ferric nitrate hexahydrate as iron source,water and N,N-dimethylformamide（DMF） as solvents,and cetyldimethy-lammonium bromide（CTAB） and sodium dodecyl benzene sulfonate（SDBS） as surfactants,respectively.The as-prepared products were characterized and analyzed by X-ray diffraction （XRD）,fluorescent spectrometry（PL） and scanning electron microscope（SEM）.Results showed that the iron oxide nano- materials had different sizes and different morphologies under the action of different solvents and surfactants.The intensity of the photoluminescence emission peak was different,and the position of the emission peak was obviously red-shifted and blue-shifted,which were mainly attributed to the different sizes and different morphologies of the iron oxide nanomaterials.
Key words： α-Fe2O3; hydrothermal method; N,N-dimethylformamide; CTAB; SDBS
