摘要：
Wurtzite ZnS nanowires were produced by a vapour-liquid-solid process. The growth mechanism of the ZnS nanowires was studied by scanning electron microscopic observations at different stages of the nanowire growth. The produced nanowires were characterized by x-ray diffraction, scanning and transmission electron microscopy and photoluminescence measurements. The ZnS nanowires were perfectly single crystalline and possess a very high aspect ratio. A photoluminescence study shows UV-blue emission from the ZnS nanowires due to the sulfur vacancy and surface states.
