ResumoElectrochemical deposition of hematite thin films was investigated on covered glass substrates. A new electrochemical method to obtain hematite thin films through a potential cycling procedure in an aqueous solution of at room temperature is presented. The electrodeposited iron oxide thin films submitted to an annealing treatment showed a good quality and crystallinity. X-ray diffraction analysis confirmed the presence of the rhombohedrally centered hexagonal structure: , hematite, as the sole crystalline phase. A bandgap energy of ca. was measured for these films.
