C. Baratto et al., Sol-gel preparation of alpha-Fe2O3 thin films: Structural characterizationby XAFS and Raman, J SOL-GEL S, 13(1-3), 1998, pp. 667-671
Films of Fe2O3 have been prepared by two different sol-gel syntheses, start
ing from inorganic salts as precursors, Fe(NO3)(3).9H(2)O or FeCl3.6H(2)O.
Differences in the local order between the two preparations are investigate
d by XAFS (X-Ray Absorption Fine Structure) and Raman measurements.
