Synthesis of tin sulfide nanoparticles by a modified solution dispersion method

In this paper, we report a novel solution route to prepare SnS nanoparticles through directly dispersing melted tin in a sulfur-dissolved solvent. Powder X-ray diffraction (XRD), transmission electron microscopy (TEM) and electron diffraction (ED) show the formation of SnS nanoparticles possessing orthorhombic structure and an average particle diameter of less than 200 nm. The as-prepared SnS nanoparticles display novel blue-UV emission, promising for applications in optical devices.
