Effect of thin layer thickness of iron oxide prepared by sol-gel on the opto-electronic properties of the material

Thin Hematite iron oxide layers ( Fe2O3) were synthesized successfully using FeCl3 as precursor, ethanol as solvent and acetic acid as catalyst according to the sol-gel process and spin-coating technique. The structural properties of the films were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Raman spectroscopy, and optical properties by the UV-Vis spectroscopy. This study shows a singular behavior of optical transmission characterized by two bearings and a clear dependence of optoelectronic parameters with film thikness.
