Fe2O3 thin films were obtained on glass substrates by the ultrasonic spray pyrolysis technique; additionally, a thermodynamic analysis on the Fe2O3 formation from different precursor salts was performed. In this work, the influence of the deposition temperature is related with the structural, optical, and morphological properties of the iron oxide films. The present results reveal that amorphous thin films are obtained at temperatures lower than 350° C, while polycrystalline films with the maghemite structure are formed at higher temperatures.
