Abstract

Wurtzite ZnS nanowires were produced by a vapour–liquid–solid process. The growthmechanism of the ZnS nanowires was studied by scanning electron microscopicobservations at different stages of the nanowire growth. The produced nanowires werecharacterized by x-ray diffraction, scanning and transmission electron microscopy andphotoluminescence measurements. The ZnS nanowires were perfectly single crystalline andpossess a very high aspect ratio. A photoluminescence study shows UV–blueemission from the ZnS nanowires due to the sulfur vacancy and surface states.
