摘要：

The preparation and luminescent properties of Eu3+-doped zinc sulfide nanocrystal were investigated. The best reactive conditions were determined, such as the concentration of reactants, the kinds and amount of the surfactants, the reaction temperature and reaction time, the pH, the flowing speed and pressure of reactive gases. The crystal structure of the nanocrystal powders was tested by X-ray diffraction (XRD). The emission and excitation spectra of ZnS:Eu were characterized by fluorescent divide spectroscopy (FDS). The luminescent sites and their strength as a function of doping Eu3+ ions are discussed. (C) 2003 Elsevier B.V. All rights reserved.
