| Abstract: | ZnS∶Eu nanoparticals were prepared via an aqueous solution with different doping concentrations.The crystal structure of the nanopowders was tested by X-ray diffraction(XRD).The luminescent property of ZnS∶Eu nanoparticals was measured by the absorption and photoluminescence spectra.The result showed all the samples were in cubic structure.Eu3+ occupied the non inversion center of symmetry of the lattice.Red emission of the samples was attributed to the 5D0→7F2 transition of Eu3+.The value of the emission intensity reached the maximum when the doped concentration was 6%(molecular ratio) and heat treatment was at 300 ℃. |
