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

Abstract

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.
