The tin sulfide (SnS) has p-type conductivity, high absorption coefficient (≥104 cm−1), bad gap energy in the range of 1.1–1.7 eV and crystalized on the cubic and orthorhombic phase [1]. The semiconductor SnS thin film is used for gas sensor and photovoltaic applications [2,3]. SnS-based layers are promising candidates for gas sensor applications compared to other layered materials such as graphene and phosphorene. For example, SnS thin film performance in chemical sensors for the detection of acetone and ethanol shows: a response of (~190%) with a fast response time of (2 s) and a recovery time of (9 s) for acetone, and a response (~130%), with a fast response time (2 s) and a recovery time (9 seconds) for ethanol, the concentration used is 10 ppm respectively [2]. The present work describes the preparation and characterization of thin films of tin (II) sulfide (SnS) by the chemical spray pyrolysis method for gas sensors applications. The layers obtained were characterized by X-ray photoelectron spectra (XPS), XPS analysis shows the existence of the constituent elements of SnS. And X-ray diffraction (XRD) that revealed the appearance of the orthorhombic phase of tin sulfide Figure 1, this phase was confirmed by vibratory modes measured by Raman spectroscopy. The optical properties such as optical conductivity, refractive-reflectivity index, extinction coefficient, and band gap energy were determined using the absorbance and transmittance data, determined by the UV-visible spectrophotometer.
