摘要

记录了亚稳晶AgCl1−xIx填充的单壁碳纳米管(SWNTs)的空间分辨电子损失谱(EELS)。高分辨率透射电镜(HRTEM)显示，掺入的卤化物晶体是由一维熔丝矿“隧道”结构产生的，其中Ag与Cl和I的配位降低，随机分布在卤素位点上。利用高分辨率EELS线扫描剖面探测纳米复合材料的局部组成，并区分填充和未填充的小管。

Spatially resolved EELS applied to the study of a one‐dimensional solid solution of AgCl1−xIx formed within single wall carbon nanotubes

Spatially resolved electron loss spectra (EELS) have been recorded for single walled carbon nanotubes (SWNTs) filled with metastable crystalline AgCl1−xIx. High resolution transmission electron microscopy (HRTEM) revealed that the incorporated halide crystals are derived from a 1D wurzite ‘tunnel’ structure with reduced Ag coordination with Cl and I randomly distributed over the halogen sites. High resolution EELS line scan profiles were used to probe the local composition of the nanocomposites and to distinguish between filled and unfilled tubules.
