Abstract
In this work, the structural and optical properties of Fe2O3 Nano-fragments suspension in ethanol were studied in detail. The optical study includes characterizing the nonlinear response of the particles by using the spatial self-phase modulation (SSPM) technique at several wavelengths (405, 532, and 650 nm). The structure and the size distribution of the collides were studied by performing X-ray diffraction (XRD) analysis, the Fourier Transformation Infrared spectroscopy (FT-IR), and Transmission Electron Microscopy (TEM) measurements. As a possible application, the potential of configuring an optical switch was also verified. The experimental results indicate that, for the amorphous Fe2O3 Nano-fragments with sizes ranging between 5-50 nm, the value of the nonlinear refractive index of Fe2O3 particles is about (0.8×10-11-2.73×10-11 m2/W) at 405nm. In addition, a pump beam at this wavelength can control any other probe beam at different wavelengths, regarding less the intensity of the probe beam. At wavelengths 532 nm and 650 nm diffraction rings cannot be formed within the light intensity used in this work (exceeding 25 MW/m2). The results of this study reveal the possibility of using these particles in optoelectronics and photonics applications.
