Abstract

The Fe doped ZnO thin films were prepared by sol-gel method assisted spin coating technique using Zn (CH3COO)2 2H2O and FeCl3.6H2O precursors as sources of Zn and Fe. Influence of iron doping into ZnO thin films were investigated by X-ray diffraction (XRD) and optical transmittance. The band gap energy and the structural parameters viz. lattice constants, average crystallite size, dislocation density stress and strain of the films were calculated. The X-ray analysis revealed that polycrystalline ZnO thin films crystallizing in the wurtzite structure and with preferred orientation along [002] direction were obtained. The average crystallite size increases with Fe concentration reaching a maximum value 21.4 nm for a concentration of 5%. The optical band gap energy of the films is found to decrease from 3.42 to 3.15 eV with increase of Fe concentration.
