Abstract

This paper deals with the preparation and characterization of iron oxide films using a simple and non-expensive technique that consists in the immersion of the glass substrates in a chemical solution composed of ferrous chloride, urea and distilled water during 1, respectively 3 hours, followed by heat treatment. The optical properties of the iron oxide films were determined using a UV-Vis spectrophotometer. An increase in absorbance was observed with the increasing of deposition time. The estimated optical band gaps of the iron oxide films were found to be 2.57 eV and 2.67 for the sample deposited for 1 hours and 3 hours respectively..
