Encapsulation of One-Dimensional Potassium Halide Crystals within BN Nanotubes

Abstract

One-dimensional crystals of potassium halides, including KI, KCl, and KBr, were inserted into boron nitride nanotubes. High-resolution transmission electron microscopy (HRTEM) and energy-dispersive X-ray spectrometry were used to characterize their microstructures and compositions. The fillings are usually single crystals with lengths up to several micrometers.
