| 摘 要： | 本文依据X射线结构数据和Raman光谱测量,分析了闪烁体ZnWO4单晶中W原子的配位情况。得出在属黑钨矿结构的ZnWO4中,认为W的配位数Z为6较4要合适些,即把发光中心看作是WO6原子基团比WO4-2离子更合适些。同时得到四条ZnWO4晶体的Raman新谱线。

| Abstract: | The coordination number Z of the atom W in scintillator ZnWO4 is analyzed based on the X-ray structural data and Raman scattering experiment results. Z is suggested to be 6 that might be more reasonable than 4. t turns out that the luminescence center in ZnWO4 locates at the configuration of the atomic group WO6, instead of WO4-2. We also present some new Raman lines expected bytheoretical analysis. |
