Abstract

This work reports the structural and optical characterization of Bi₂S₃ nanoparticles, which were synthesized using colloidal chemistry by reacting bismuth nitrate and thioglycolic acid in aqueous medium. Our synthetical approach produces well-crystallized Bi₂S₃ nanoparticles as indicated by XRD, TEM and Raman spectroscopy analyses. The nanoparticles crystallized in the orthorhombic phase of Bi₂S₃, and displayed Raman vibrational bands around 117, 129, 192 231, 240 and 312 cm^-1. TEM analysis reveals that the Bi₂S₃ particle size varies characterization, the particle size varies in 2-15 nm range.
