未掺杂和掺Li的CdWO_4闪烁晶体的电子自旋共振研究
Electron Spin Resonance investigation of undoped and Li-doped CdWO_4 scintillator crystals
摘要：
本文研究了标称纯CdWO_4和掺0.05%Li的CdWO_4单晶中Fe ~（3+）和Mn ~（2+）离子的电子自旋共振（ESR）谱。对这两种杂质的零场分裂参数进行了高精度的测定。结果表明，锂的掺杂导致铁的离子电荷从3+增加到4+，锰的离子电荷从1+增加到2+。
英文摘要：
Electron spin resonance (ESR) spectra of Fe3+ and Mn2+ ions have been studied in the nominally pure and 0.05% Li-doped single crystals of CdWO4. The zero-field splitting parameters are determined with a high precision for both of the impurities. The result suggest that the Li-doping leads to the increase of the ionic charge of iron from 3+ to 4+ and of manganese, from 1+ to 2+.
