The possible reason is that doped Zr〓 ion enters the interstitial sites for its small ionic radius and no dipole complexes were formed. Monovalent ion F〓 has been reported to improve the scintillating performance greatly. Our results show that Agrand diagrams of F〓: PWO crystals obey an modified Cole-Cole equation. The crystals present similar dielectric relaxation phenomena to but have much higher activation energy than that of RE〓: PWO crystals, which originate from the 〓 dipole complexes. The co-doping of trivalent Y〓 and pentavalent ion Nb〓 does not always show a better scintillation performance than that of solely doped samples, which could be attributed to the existence of the 〓 dipole complexes, which counteract the solely doping effect.

而Zr〓由于离子半径太小，可能进入间隙位置，不形成类似的偶极缺陷；一价负离子F〓的掺入提高了晶体闪烁性能，阻抗谱测试结果表明F〓：PWO晶体Argand图符合修正的Cole—Cole方程，晶体同样表现出介电弛豫现象，并具有比RE〓：PWO晶体中高得多的弛豫激活能，可能起源于形成的〓偶极缺陷；Y〓和Nb〓双掺的PWO晶体并没有显示出两种离子单掺优点的叠加，阻抗谱测量结果表明，在双掺晶体中可能形成〓偶极缺陷，使两者掺杂作用相互抵消。
