借助ＴＥＭ、ＸＲＤ、硬度微观测量等方法，研究了卤化银多晶红外光纤的显微结构与相关性能的关系．发现光纤是以ＡｇＣｌｘＢｒ１－ｘ。多晶体为主骨架，纳米晶粒Ａｇ镶嵌其中．由纳米晶粒带来的损耗光纤的散射损耗增加很小，即ＡＮλ－４通过控制光纤的制备工艺条件，可以改变光纤的晶粒大小和光纤硬度．
TEM, XRD, hardness measurement were employed to analyze the microstructure ofsilver halide polycrystalline infrared fiber. The polycrystals are the host of the fiber with mosaicAg nanocrystals. The fiber microstructure has an effect on the scattering loss. The fiber grain sizeand microhardness can be changed through different processing.
