Abstract

The melt phase encapsulation of gadolinium iodide (GdI3) in small internal diameter carbon nanotubes (CNT) was explored to understand how the tubular structure of the host could chemically stabilize a hygroscopic metal halide. However, given the distribution of diameters in the as-received CNTs, the final sample consisted of mixed encapsulation products. These varied from the mono-elemental iodine chain to the atomic layer deposition of the binary halide. Supported by density functional theory calculations, these observations led to the proposition of a morphological phase diagram for GdI3 encapsulation in CNTs as a function of the host’s internal diameter.
