Abstract

Fe₂O₃-SiO₂-CTAB transparent nano-composite films were prepared by means of a two-step acid-catalyzed method and sol-gel process using surfactant cetyltrimethylammonium bromide (CTAB) as template and tetraethoxysilane (TEOS) as the starting material, iron nitrate Fe(NO₃)₃·9H₂O as iron source material. Optical properties, structural and magnetic characteristics of the films were investigated by UV-visible spectra, FT-IR spectra and vibrating sample magnetometer (VSM). The transparency of the high temperature treated Fe₂O₃-SiO₂-CTAB nano-composite films exceeds the glass substrate. It is also found that the saturation magnetization (Ms) of the films increases with the treating temperature. The magnetization measurements reveal that Fe₂O₃-SiO₂-CTAB nano-composite films display normal ferromagnetic behaviors. It is also shown that the CTAB plays a key role in the optical and magnetic properties of Fe₂O₃-SiO₂-CTAB composite films.
