Preparation and Characterization of Iron(III) Oxide Films by a Novel SprayPyrolysis Method

摘要

Various techniques have been employed for the preparation of iron oxide filmssuch as pulsed laser evaporation, sputtering, sol-gel processes, chemical vapor deposition, and spray pyrolysis. Films of iron oxide deposited using a spray pyrolysis technique have been identified as Fe2O3 by conversion electron Moss-bauer spectroscopy and X ray analysis. IR spectra of polycrystalline Fe2O3 have been studied extensively. However, the position, width, and relative intensity of the observed absorption bands lack consistency, and depart from theoretical expectations. This discrepancy is caused by the diversity in the size and shape of the sample particles.
