摘要
钨酸铅（ＰｂＷＯ４）晶体在生长过程中由于缺氧产生了氧空位缺陷和Ｆｅ２＋杂质缺陷，使晶体着色，光学性能下降。在晶体生长过程中掺进Ｓｂ２Ｏ３，能消除氧空位，将Ｆｅ２＋氧化为无色的Ｆｅ３＋。
Oxygen vacancy defects and Fe 2+ impurity defects were produced in PbWO 4 crystal growth process due to oxygen deficient, which lead to the coloration of the crystal and the optical properties lower. Doped Sb 2O 3 into the crystal, the oxygen vacancy had been dispeled, and Fe 2+ had been oxidized to Fe 3+ which is colourless. The optical properties and the scintillation characteristics has been enhanced.
