摘要

Fe_2O_3 nano-particles are synthesized by mechanical milling at room temperature. Dry milling technique has been found to be effective method of particle size reduction of Fe_2O_3. The particle size and lattice strains have been determined by x-ray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM). For studying optical properties, UV-Visible and photoluminescence (PL) spectroscopy have been done. The results reveal that different milling conditions influence the optical properties. This stud y also reveals that not only the surface layer but the inter facial regio n between the α and γ phases also plays an important role for photoluminescence emission of ultra fine nanoparticles invisible light region.
