The effect of annealing temperature on the optical properties of In2S3 thin film

Indium Sulfide (In2S3) thin film were deposited on glass substrate through successive ionic layer adsorption and reaction (SILAR) method. The samples were annealed at 250 °C, 350 °C and 450 °C respectively after deposition. The X-ray diffraction (XRD) analysis shows that the sample annealed at 450 °...

Description
Summary:Indium Sulfide (In2S3) thin film were deposited on glass substrate through successive ionic layer adsorption and reaction (SILAR) method. The samples were annealed at 250 °C, 350 °C and 450 °C respectively after deposition. The X-ray diffraction (XRD) analysis shows that the sample annealed at 450 °C has the most clear and obvious XRD pattern, which indicates that In2S3 annealed at 450 °C possess the highest crystallinity. Ultraviolet-visible spectroscopy analysis of the samples shows that the band gap of In2S3 is around 2 eV. This study shows that annealing does not induce any change in optical bandgap of In2S3 thin films on glass substrates as reported elsewhere.
