Abstract

In this work, we prepared Fe2O3 thin films using a pulsed laser deposition method. The Nd:YAG laser is used to prepare Fe2O3 films on a glass substrate under a temperature of 200°C, and the effects of laser energy on the structure and optical properties of thin films have also been studied. The optical properties of the absorption and transmission spectra of the formed thin films were studied. The direct bandgaps of the samples were obtained by measuring the absorption and transmittance spectrometers ranging from 2.3 to 2.7 eV. Using atomic force microscopy (AFM) technique and taking pictures, the surface structure of the formed films was studied. The size of the nanoparticle grains is observed in the range of (73.87), (69.28) and (102.38) nm for energy (700, 800, 900)mJ, respectively.
