Synthesis and Size Dependent Reflectance Study of Water Soluble SnS Nanoparticles

Near-monodispersed water soluble SnS nanoparticles in the diameter range of 3-6 nm are synthesized by a facile, solution based one-step approach using ethanolamine ligands. The optimal amount of triethanolamine is investigated. The effect of further heat treatment on the size of these SnS nanoparticles is discussed. Diffuse reflectance study of SnS nanoparticles agrees with predictions from quantum confinement model.
