摘　　要：以醋酸锌和硫代硫酸钠为原料,十六烷基三甲基溴化铵(cetyltrimethyl ammonium bromide,CTAB)为表面活性剂,低温简单水热法合成了ZnS微球。通过XRD、TEM、SEM、FT-IR等表征手段对产品ZnS微粒进行了结构和形貌分析。结果表明:ZnS粒子为微球结构,属于立方闪锌矿结构,粒径在3μm左右,且分散性良好,球形度高;在1 116 cm-1、618 cm-1、495 cm-1处出现Zn—S键的红外特征吸收峰。同时对ZnS微球的可能生长机理进行了探讨。Monodispersed ZnS microspheres were hydrothermally synthesized under low temperature using zinc acetate and sodium thiosulfate as raw materials,and cetyltrimethyl ammonium bromide（CTAB） as surfactant.The particles were characterized by XRD,TEM,SEM and FT-IR.The results showed that the smooth particles were of cubic phase,well-dispersed and had uniform size of 3 μm in diameter,and the characteristic absorption peaks of Zn—S appeared in the FT-IR spectra.Also,the possible growth mechanism was discussed.
