Abstract

Effect of heat treatment on the optical and morphological properties of iron oxide thin films prepared by spray pyrolysis

Author(s): Salam Amir Yousif

Transparent thin films of Iron oxide have been deposited on a glass substrate at 400°C by simple and costeffective chemical spray pyrolysis technique. The effect of heat treatment on the optical and morphological properties of Fe2O3 thin films have been investigated. The transmittance of Fe2O3 thin films increase with increasing annealing temperature. The sampleswere also analyzed by atomic force microscopy (AFM) and they reveal grainmorphology common for polycrystalline films. The root mean square roughness and grain size of the as grown and annealed Fe2O3 thin films have been studied.
