Abstract

Abstract : Crystalline antimony sulfide (Sb2 S3 ) with nanorods morphology was successfully prepared via hydrothermal method by the reaction of elemental sulfur, antimony, and iodine as starting materials with high yield at 180 ∘ C for 24 h. Using oxidation reagent like iodine as an initiator of redox reaction to prepare Sb2 S3 is reported for first time. The powder X-ray diffraction pattern shows the Sb2 S3 crystals belong to the orthorhombic phase with calculated lattice parameters, a = 1.120 nm, b = 1.128 nm, andc = 0.383 nm. The quantification of energy-dispersive X-ray spectrometry analysis peaks gives an atomic ratio of 2 : 3 for Sb : S. TEM and SEM studies reveal the appearance of the as-prepared Sb2 S3 is rodlike which is composed of nanorods with the typical width of 50–140 nm and length of up to 4 μ m. The PL emission indicates that band gap of Sb2 S3 is around 2.50 ev, indicating a considerable blue shift relative to the bulk. A formation mechanism of Sb2 S3 nanostructure is proposed.
