Abstract
We report the synthesis of bulk prismatic single crystals of M 2S 3 (M = Sb, Bi) via a novel hydrothermal process, using SbCl 3 or BiCl 3 and sulfur as the raw materials at 180 °C for over 7 days in the presence of diethylammonium chloride (DEACl) or tetraethylammonium chloride (TEACl), and Sb 2S 3 nanorods through a similar process in the presence of hydrazine hydrate. The products were characterized by various techniques, including X-ray powder diffraction (XRD), X-ray single crystal diffraction and field emission scanning electronic microscope (FESEM). The possible growth mechanism of single crystals was also discussed.
