AgI纳米粒子水溶胶的制备与表征

Preparation and Characterization of AgI Nanoparticles Hydrosol

摘要:

采用沉淀法制备了AgI纳米粒子水溶胶，对制备水溶胶的条件进行了系统的研究。TEM分析表明，AgI纳米粒子呈球形，粒径小于50nm，粒径分布均匀，无明显团聚现象；ED分析表明，AgI纳米粒子为多晶结构，其中有少量的发育良好的单晶颗粒存在。

Abstract:

AgI hydrosol was prepared by the precipitation method and the effect factors on hydrosol were discussed systematically. TEM photos show that the AgI nanoparticles are spherical in shape , the size of which is less than 50nm.The particle size distribution: in a anarrow range, and no agglomerate has been observed. ED images indicate that the AgI nanoparticles are polycrystalline structure, and some are well-grown monocrystalline particles.
