摘要：
Wurtzite-type ZnS : Mn2+ nanowires were prepared by a hydrothermal method at 180 degrees C without any surface-active agent. The structure and morphology of the samples were characterized by x-ray diffraction, transmission electron microscopy, high-resolution transmission electron microscopy, Fourier transform infrared spectroscopy and energy dispersive spectroscopy. The average diameter of the nanowires was about 10 nm. An ethylenediamine-mediated template was observed and employed to explain the growth mechanism in detail. A strong yellow-orange emission from the Mn2+ (4)T(1-)(6)A(1) transition was observed in the photoluminescence spectra, which exhibited blue shift as the Mn2+ doped ratio increased.
