摘　　要：采用溅射法在玻璃表面溅射上一层金属银,在室温下与碘的乙醇溶液反应,制备纳米碘化银薄膜。探讨银的厚度、反应时间、表面活性剂及用量对晶体生长的影响,用X射线衍射和扫描电子显微镜表征样品。结果表明,最佳条件下制得碘化银粒径为50nm左右的碘化银薄膜,相转变温度滞后13℃,使得具有高电导率的α相碘化银可在更低的温度下稳定存在。The nano-Ag I thin film is synthesized by the reaction of the silver film with I2 ethanol solution at ambient temperature,the silver film is sputtered on the glass in advance. The influences of the thickness of sputtered silver,reaction time,the type and dosage of the surfactant on the growth of crystal are investigated. The resultant films are characterized by X-ray diffraction（ XRD） and scanning electron microscopy（ SEM）. The results show that the average diameter of the Ag I film product obtained at the optimal condition is 50 nm,and the phase transition is lagged with 13 ℃,so the α-phase Ag I with highconductivity can exist at the lower temperature.
