用激发-发射光谱研究了稀土离子（REE = Pr，Sm，Eu，Gd，Dy，Ho，Er）掺杂锆英石（ZrSiO 4）的光致发光特性。所有样品均表现出与其他镧系元素掺杂材料相似的离子内能量跃迁发光特性。然而，相对强度依赖于激发的能量，并且从激发光谱推断电荷转移带的存在。从数据中，我们得出结论，镧系元素在锆石中出现在一个以上的配位类型。在一些共掺杂样品中观察到不同镧系元素之间的能量转移，并且基于激发光谱将先前研究中未分配的发射分配给特定的镧系元素。
The photoluminescence properties of synthetic zircon, ZrSiO4, doped with REE3+ (REE = Pr, Sm, Eu, Gd, Dy, Ho, Er) were investigated using combined excitation and emission spectroscopy. All samples showed luminescence characteristics of intra-ion energy transitions, similar to other lanthanide-doped materials. However, the relative intensities were dependent on the energy of excitation and the presence of charge-transfer bands were inferred from excitation spectra. From the data, we conclude that the lanthanides in zircon occur in more than one type of coordination. Energy transfer between different lanthanides was observed in some co-doped samples and emissions that were unassigned in previous studies have been assigned to specific lanthanides based on excitation spectroscopy.
