Abstract

By refluxing antimony trichloride (SbCl3) and thiourea in various solvents at suitable reaction conditions, antimony sulfide (Sb 2S3) crystallites with a diversity of well-defined morphologies were synthesized. Sb2S3 rods with the average diameter of 800nm and the length of 7 μm, as well as microtubes with the average outer diameter of 1.2 μm, the average inner diameter of 800nm and the length of 8 μm, were obtained in 1,2-propanediol at 180°C for 10 min. In contrast, a series of experiments under different conditions were carried out to investigate the influencing factors on the reaction. The as-synthesized products were characterized by powder X-ray diffraction, field-emission scanning electron microscopy, transmission electron microscope and X-ray photoelectron spectra. The results indicate Sb2S 3 crystals with different morphologies, including rod-like, tube-like, bowknot-like, flower-like, straw-bundled-like, taken under different experimental conditions. It is found that the reaction temperature, time, solvent and poly(vinyl pyrrolidone) (as a polymer capping reagent) play important roles in the formation of the final Sb2S3 crystallites with different morphologies. Also, the possible growth mechanism is discussed.
