So far, various techniques have been used attempting to prepare Fe-doped ZnO thin films through chemicalmethods, such as sol–gel, spray pyrolysis, citrate decomposition and hydrothermal as well as physical methods, such as RF sputtering and pulsed laser deposition. Due to cost effectiveness, simple deposition procedures, no need of vacuum deposition conditions, possibility producing large film, excellent compositional control, being able to deposite thin films on complex-shaped substrates, etc. the sol–gel technique was widely employed and considered as a promising technique for the production of Fe-doped ZnO thin films in future. In previous studies, some research groups prepared Fe-doped ZnO thin films by magnetron sputtering and investigated their physical properties [24,25], but few groups prepared Fe-doped ZnO thin films by sol–gel spin coating [26] or dip coating [27] method to investigate their structural, electrical and optical properties. Limited information is available on the magnetic properties of Fe-doped ZnO thin films fabricated by the sol–gel dip coating technique. The main objective of this study is to synthesize nanostructured Fe-doped ZnO thin films by sol–gel technique and study their structural, optical, and magnetic properties as a function of Fe-doping.
