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.
