The Influence of Temepature on the structural and optical properties of Sb2S3 thin films prepared by chemical bath deposition method

Abstract

In this study we used chemical bath deposition method for deposited Sb2S3 thin films on glass substrate. The study analyzed the optical properties and structural characterization of Sb2S3 thin films. The structural properties were studied on the thin films by x-ray diffraction (XRD), Scanning electron microscope (SEM), Energy dispersive X ray Analysis (EDAX). The XRD pattern showed that the thin films were polycrystalline, and EDAX showed that the constituents of the element were found to be chemically balanced and convergent peak (ie, verification chemical balance of phase Sb2S3).The optical properties showed that the optical energy gap at 40°C is 2.8 eV ,and at 50 °C is 2.6 eV , and the optical transmittance at 40°C is %80,and at 50°C is reached about %60.
