| Abstract: | Copper indium sulphide (CIS) nanoparticles were prepared using ultrasound-assisted precipitation, by simultaneous addition of reagents. The Cu-In ratios was varied in order to study its effect on morpho-structural characteristics of CIS. Depending on the composition, the surface area of CIS powders varies between 35.3-114.3 m2 /g and the energy band gap between 1.4-2.9 eV. The morphology, structure and optical properties of the samples were highlighted by UV-Vis spectroscopy, XRD, TEM and BET analysis. The experimental amount of Cu-In ratio was determined based on ICP-OES results and the energy band gap is calculated from UV-Vis spectra using Tauc’s relation. |
