Paper Abstract

Films of (alpha) -Fe2O3, whose high non-linear optical susceptibility (chi) (3) has been recently reported, have been prepared by the sol-gel method using two different sol-gel syntheses, both starting from inorganic salts as precursors, Fe(NO3)3-9H2O or FeCl3- 6H2O. Thermal treatments on films obtained by dip coating lead to the (alpha) -Fe2O3 hematite structure for both preparations as indicated by XRD, Raman and X-Ray Absorption Spectroscopy measurements.
