Abstract

Abstract: Nanoparticles of Sb2−x Bix S3 (x = 0.0, 0.002, 0.006, 0.01) are synthesized by chemical precipitation technique at room temperature and characterized by powder x-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive analysis of x-rays (EDAX), room temperature and low temperature Raman spectroscopy. The Rietveld refinement profiles of powder XRD patterns reveals that the prepared nanoparticles are crystallized in stibnite orthorhombic structure with Pnma space group and do not contain any other impurity phase. TEM images show nearly spherical shape of Sb2−x Bix S3 (x = 0.0, 0.002, 0.006, 0.01) nanoparticles whereas selected area electron diffraction (SAED) patterns indicate polycrystalline nature. EDAX analysis confirmed the purity of the prepared nanoparticles. The different vibration modes in Sb2−x Bix S3 (x = 0.0, 0.002, 0.006, 0.01) nanoparticles is studied by room temperature and low temperature (up to 80 K) Raman spectroscopy.
