Morphology evolution of SnS nanocrystals: from 3D urchin-like architectures to 1D nanostructures

Elegant 3D SnS urchin-like architectures have been successfully prepared using SnCl2·2H2O and KSCN as starting materials in ethylene glycol under a mild solvothermal condition. The morphological transformation from 3D frameworks into 1D nanostructures has been observed, which were strongly dependent on the prolonged reaction time. The prepared products were characterized by various techniques, such as XRD, XPS, FESEM, TEM and ED. The possible formation mechanism was also discussed.
