Study of optical properties of manganese doped ZnS nanocrystals

ZnS:Mn nanocrystals were prepared by the coprecipitation method. The reaction conditions, such as the amount of manganese doped, the concentration of the reactant, the surfactant, the reactive temperature and time were studied systematically. Nanocrystalline powders and sols exist. The photoluminesc...

Description
Summary:ZnS:Mn nanocrystals were prepared by the coprecipitation method. The reaction conditions, such as the amount of manganese doped, the concentration of the reactant, the surfactant, the reactive temperature and time were studied systematically. Nanocrystalline powders and sols exist. The photoluminescent excitation spectra and the photoluminescence spectra of ZnS:Mn nanocrystal were studied by the fluorescent divide spectroscopy under an ultraviolet excitation. It is shown that the luminescent sites of the nanocrystalline powder and sol are different from that of ZnS:Mn bulk crystal. The luminescent site of the sample results from the transition of the doped Mn 2+ in the ZnS crystal.
