Sb:ZnWO_4晶体生长及其闪烁性能研究

Studies on the Growth of Sb:ZnWO_4 Crystal and Its Scintillation Properties

本文报道了用分析纯的 WO_2和 ZnO 为原料,并在其中掺加适量的 Sb_2O_3杂质,提拉法生长出无色的 Sb:ZnWO_4的研究结果。测量了晶体的透过率、发光效率、能量分辨率和发射光谱。对Sb_2O_3在 ZnWO_4晶体中的消色机理进行了初步探讨。

In this paper the growth of Sb:ZnWO_4 crystals is reported.The transmission,luminescence efficiency,energy resolution and emissionspectrum of the Sb:ZnWO_4 crystal have been measured,and the decolourizationmechanisum of Sb_2O_3 in ZnWO_4 crystals have been discussed.
