Paper Abstract

Layered two-dimensional (2D) transition metal chalcogenides have attracted incredible interest due to their intriguing electronic, electrical, and optical properties. Liquid phase exfoliation (LPE) technique has been employed for the synthesis of ultrathin tin sulfide (SnS) sheets. A many body process, exciton-exciton annihilation was found to be significant in such anisotropic nanosheets of reduced dimensionality. Moreover, femtosecond Z-scan measurement infers that these 2D materials exhibit saturable absorption property because of optical transitions, which result in band filling from low to high energy band. The value of non-linear absorption coefficient was found greater and saturation intensity was found lower than that of other 2D materials. By taking the advantage of high nonlinear absorption coefficient and low saturation intensity ultrathin SnS nanosheets may prove to be a suitable candidate for various applications like saturable absorber, Q-switching.
