摘要
改进传统的共沉淀法 ,由Ag(NH3 ) 2 + 与KI溶液混合 ,制备了均匀球形的AgI纳米粒子 ,研究了反应条件(银配合物浓度、氨浓度、反应时间等 )对AgI粒子形态的影响 ,并进行了X射线衍射及透射电镜的分析 .
The uniform spherical nano-particles of AgI have been prepared by silver complex, which improved the procedures of the used co-precipitation. Some factors(as the concentration of silver ion and complex ions of ammonia, and reaction time) strongly affect the size and shape of AgI particles. Diameter of AgI particles could be changed from 20 to 100 nm. XRD and TEM were measured in this study.
