摘要：

A simple two-step approach for the assured filling of single-walled carbon nanotubes (SWNT) channels with AIIBVIand A IVBVI chalcogenide 1D nanocrystals was reported. The method is based on the formation of intermediate metal iodide in SWNTs using a molten media technique with subsequent chalcogenation reaction performed in molten chalcogen. The first experiments were aimed to grow 1D CdS nanocrystals inside SWNT channels. An impregnation of single-wall carbon nanotubes with low-melting cadmium iodide followed by sulfidizing in molten sulfur was performed. The evidence for filling nanotubes and the structure of encapsulated particles was investigated using JEM-3000F JEOL and FEI Titan 80-300 Cs-corrected field emission transmission electron microscopes (TEMs) equipped with an INCA Energy + Oxford EDX analyzer. The iodine formed during substitution reaction was found by mass spectrometry of sublimate byproduct collected on the cooler part of the quartz ampule.
