摘要
对银纳米晶的系列样品进行了XRD微结构实验研究和计算。结合所得到的晶粒度和微结构参数发现纳米银晶粒组元中存在着晶格畸变;随着晶粒尺寸的变化,银钠米晶的微结构呈现出明显的变化,其晶格畸变与晶粒度有着比较密切的关系。
The microstructures of nanocrystalline silver were systematically investigated with XRD. We found thatthere exist some lattice distortion in the silver single crystal nanoparticles; and the microstructures change with the increase of nanoparticle sizes. Our calculation and XRD observations revealed tha lattice distortion correlates to crystallitesizes.
