The nanostructured SnS thin films were obtained by a low-cost chemical spray pyrolysis method (CSP). The optical and structural parameters of SnS nano ﬁlms were studied by different thickness. X-ray diffraction showed that ﬁlms were of orthorhombic structure with preferred orientation in the (111) direction. These ﬁlms reveal a decrease in crystallite due to thickness film increasing. Results indicated that ﬁlms showed < 70% of transparency in visible region. The same behavior was noticed for the optical bandgap. Results obtained by dispersion parameters mention thickness dependency.
