A facile one-step chemical method has been developed for synthesize of SnS-based nanocomposites. Herein, we have prepared a series of SnS based nanocomposites such as SnS/CdO, CdO/SnS, SnS/PbO, PbO/SnS, SnS/PbS and PbS/SnS. The synthesized nanocomposites were characterized using X-ray diffraction (XRD), transmission electron microscope (TEM), Fourier transform infrared (FT-IR), UV-visible and Photoluminescence (PL) spectroscopy. The obtained results are discussed in details.

Significant PL sifting observed for SnS based nanocomposites. The role of the various compounds added with SnS is mainly for tunning the optical emission of the SnS. The obtained visible light emission of the SnS-based nanocomposites can be used in the optoelectronic applications.
