Pyrrole-added Fe2O3 films by ultrasonic spray pyrolisis

Pyrrole-added Fe2O3 films by ultrasonic spray pyrolisis

Fe2O3 thin films were grown by Ultrasonic Spray Pyrolisis from a 0.05 aqueous solution of FeCl3 added with a small amount of pyrrole monomer. Films at different substrate temperature and pyrrole content were grown. They were characterized by using x-ray diffraction (XRD), infrared spectroscopy (FTIR) and atomic force microscopy (AFM). Results indicated that at low substrate temperature (approximately < 200°C) the films mainly resemble the polypyrrole structure. At higher temperatures up to 400°C the trend is to form the hematite phase (Fe2O3) of iron oxide. Furthermore, the surface morphology exhibits nano-size features, which can be changed by using different pyrrole contents. This last feature could be useful for usage of the film as a gas sensor.
