Abstract	CuInS₂ nanoparticles were synthesized by a simple sonochemical method; First, Cu nanoparticles were prepared from CuCl₂ in methanol solution by a one pot reaction through the sonochemistry under multibubble sonoluminescence (MBSL) conditions. Second, the resulting Cu nanoparticles were treated with InCl₃?4H₂O and CH3CSNH2 (thioacetamide) at the same MBSL conditions to synthesize In₂S₃-coated Cu nanoparticles in methanol solution. Then, they were transformed into CuInS₂ (CIS) nanoparticles of 20 ~ 40 nm size in diameter by thermal heating at 300 oC for 2 hr. The prepared CIS nanoparticles, of which band gap is 1.44 eV, were investigated by X-ray diffractometer, UV-Vis spectrophotometer, inductively coupled plasma spectrometer, and high resolution-transmission electron microscope.
