Metastable One-Dimensional AgCl₁_-<i>_x</i>I<i>_x</i> Solid-Solution Wurzite “Tunnel” Crystals Formed within Single-Walled Carbon Nanotubes

Abstract

High-resolution transmission electron microscopy and spatially resolved electron loss spectroscopy have revealed that a eutectic mixture of AgCl and AgI crystallizes within single walled carbon nanotubes (SWNTs) as metastable AgCl(1-)(x)I(x) 1D solid solution crystals. The incorporated halide crystals form wurzite "tunnel" structures with locally varying Cl:I ratios and reduced Ag coordination.
