摘 要：Copper indium disulfide（CuInS2） nano-particles were synthesized by solvothermal method at 150 ℃ using copper（?） chloride,indium（Ш） chloride,thiourea and ethanol as raw materials,and characterized by X-ray diffraction（XRD）,field-emission scanning electron microscope（FESEM）,and UV-Vis spectra.The effects of pH value on its micro-structures and optical properties were investigated.The results show that,with the pH value increasing,the particle size of the nano-crystalline CuInS2 increases,and its band gap becomes narrower under alkaline condition.The band gaps of CuInS2 nano-particles are from 1.52 eV to 1.93 eV,which makes them promising candidates as absorber materials for photovoltaic applications.
