Nanosized ZnS doped with different concentrations of Eu³⁺ were prepared and analyzed by x-ray diffraction technique. The experimental results show that ZnS belongs to the cubic structure. From the photoluminescence (PL) emission spectra, it can be seen that the ratio of the emission intensity of Eu³⁺ at 616 nm to that at 590 nm increases as the increasing of Eu³⁺. This phenomenon reveals that the site symmetry of Eu³⁺ reduces as the increasing of Eu³⁺.
