Abstract. Tin sulfide is a promising optoelectronic material which has a particular interest due to its absorption coefficient, a direct bandgap 1.7 eV and its non-toxic components. SnS thin films were deposited on glass substrates by successive ionic layer adsorption and reaction (SILAR) method. The cationic and anionic solutions are SnCl2.2H2O and Na2S.9H2O respectively, were used as precursors materials. The structure, film composition, morphology, and optical properties were investigated by using X-ray diffraction, energy dispersive X-ray analysis, Scanning electron microscopy (EDX-SEM) and spectrophotometer. X-ray diffraction (XRD) patterns indicated that the deposited SnS thin films have orthorhombic crystal structure. Uniform deposition of the material over the entire glass substrate was showed by Scanning electron microscopy (SEM). The optical band gap energy was found to be 1.7 eV.
