Abstract
Two different sol-gel syntheses, both starting from inorganic salts as precursors, Fe(NO3)(3) . 9H(2)O or FeCl3 . 6H(2)O, have been employed to prepare, by dip-coating, films of alpha-Fe2O3, which are currently investigated for their high non-linear optical susceptibility chi((3) ). Thermal treatments at 500 degrees C lend to the alpha-Fe2O3 hematit e structure for both preparations as indicated by XRD and Raman. Infor mation on the differences in the local order between the two preparati ons are obtained by X-ray absorption spectroscopy (XAS) measurements. (C) 1998 Elsevier Science B.V.
