Nanosized Films of Fe2O3 : Hematite Films Intercalated by Lithium

Thin-films containing nanosized grains of Fe2O3 are widely used in research into mainly magnetic and electronic devices [1]. Our intention is to construct charge-discharge Fe2O3-electrode battery with polymer electrolyte and to attach it to solar-cells [2]. Films of iron oxide derived by the chemical deposition method route were investigated by the impedance spectroscopy (IS), SEM, and XRD in order to establish the relation between electrical and the structural properties in nanostructured Fe2O3 and Fe2O3: Li (1% and 10%) films on glass substrate. IS was applied to measure the resistance of nanostructured Fe2O3 films with different contents of lithium. By SEM and XRD measurements, we have determined, besides the hematite nature of our samples, that they are composed of the nanosized crystalline grains in the size range from 10 nm to 200 nm. We have also found samples’ steadiness during the eight-month period.
