Abstract: In2S3 thin films were prepared using chemical spray pyrolysis technique. All films were deposited on FTO (Fluorine Doped Tin Oxide) coated glass substrate with different temperatures. The films obtained were characterised by X-ray diffraction (XRD), scanning electronmicroscopy (SEM,) optical transmission spectra, energy dispersive spectroscopy (EDS) and Atomic force microscopy (AFM). XRD studies have revealed that the samples are -In2S3. All the films grown exhibited transparency over 55 % in the visible spectral region. According to SEM, the surface morphologies of the films were free of defects. The AFM micrograph show that the films adhered to the FTO substrate with a small grain size. The optical band gap energy varied from 2.73 eV to 2.90 eV.
