中文摘要：

文章采用两种方法合成了Ag2S：以溅射过银的导电玻璃、硫粉和NaOH为反应物，在水中合成了Ag2S；以溅射过银的导电玻璃、硫粉和叔丁醇钾为反应物，在乙醇中合成了Ag2S。采用X射线衍射（XRD）和扫描电子显微镜（SEM）对Ag2S的形貌以及晶体结构进行了表征。结果表明，制备出的Ag2S分别为1μm左右的颗粒和为30nm左右的小颗粒，均为单斜结构。

英文摘要：

To prepare Ag2S, a series of methods were used in this paper. We obtained Ag2S by using the silver film on the ITO substrate, S powder and NaOH as raw materials in water. Ag2S was prepared by using a silver film on the ITO substrate, S powder and potassium tert-butoxide as raw materials in ethanol. The morphology and crystalline structures of the synthesized Ag2S was characterized by X-ray diffraction （XRD） and scanning electron microscope （SEM）. The results show that Ag2S obtained are about 1μm or 30nm and all exhibit a typical monoclinic structure.
