摘 要：CuS pineal microspheres congregated from interleaving nanoflakes with thickness of 40 to 200 nm were synthesized by a pyridine-solvothermal process via the reaction between cupric chloride（CuCl2·2H2O） and thioacetamide（TAA,CH3CSNH2）.The products were characterized by X-ray diffraction and scanning electron microscopy.UV-Vis absorption spectrum,excitation and photoluminescence spectra of CuS pineal microspheres were obtained at room temperature to investigate their optical properties.A possible growth mechanism on the formation of CuS pineal microspheres is proposed.The factors influencing the evolution of morphologies of CuS crystals including the dosage of the reactants,surfactant,and sulphur-source were also analyzed.
