的FD-跃迁能量的Ce 3+，在无机化合物上的数据进行比较与Eu 2+在相同的化合物。尽管存在不同的电荷补偿缺陷，但它们之间存在明显的相关性，Eu ~（2+）和Ce ~（3+）的吸收红移、发射斯托克斯位移、5d组态的质心位移以及5d能级的总晶场分裂都呈现线性相关。Eu ~（2+）的值约为Ce ~（3+）的0.7倍。这意味着可以采用Ce 3+已知的光谱性质来粗略预测Eu 2+的光谱性质，反之亦然。对Ce ~（3+）和Eu ~（2+）的研究结果可以推广到所有三价和二价镧系元素。
Data available on the fd-transition energies of Ce3+, in inorganic compounds are compared with those of Eu2+ in the same compounds. Despite differing charge compensating defects, clear correlation was found. The redshift of absorption, the Stokes shift of emission, the centroid shift of the 5d configuration and the total crystal field splitting of the 5d levels of Eu2+ and Ce3+ all appear to be linearly related to one another. The values for Eu2+ are about 0.7 times those for Ce3+. This implies that spectroscopic properties known for Ce3+ can be employed to roughly predict spectroscopic properties for Eu2+ and vice versa. The findings for Ce3+ and Eu2+ can be generalized to all trivalent and divalent lanthanides.
