Synthesis of Coral‐Like, Straw‐Tied‐Like, and Flower‐Like Antimony Sulfides by a Facile Wet‐Chemical Method

Abstract

Antimony sulfide (Sb 2 S 3 ) was successfully synthesized from antimony chloride (SbCl 3 ) and sodium thiosulfate pentahydrate (Na 2 S 2 O 3 ⋅ 5H 2 O) in ethylene glycol (EG) without using any template by a facile wet-chemical method. X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) show that the products were orthorhombic Sb 2 S 3 nanorods forming the coral-like, straw-tied-like, and flower-like architectures with the nanorods growing along the [001] direction. The energy gap (E g ) was determined by UV-visible absorption to be 1.52 eV.

SOLVOTHERMAL SYNTHESIS OF Sb2S3 NEEDLES AND STUDY OF THE EFFECT OF THEIR INTERGROWTH ON THEIR OPTICAL PROPERTIES

“…Kavinchan et al obtained flowerlike structures by means of a solvothermal process. Spherical structures of about ~8 μm in diameter, consisting of fine wires, have also been obtained [14]. Lu et al reported the synthesis of Sb 2 S 3 bars by the hydrothermal route attaining bars of 5 μm in length that were coupled in different directions [15].…”
