除了已知的Eu3+在Y2O3中对称c2in晶格上的能级外，还发现了该离子在同一主体晶体中对称c3in晶格上的一些跃迁，从而有可能部分地构建该能级图式。给出了从Eu3+(C3i)到Eu3+(C2)的能量转移的证据，其强度作为eu2o3浓度的函数进行了测量。这些结果导致假设负责能量传递的相互作用有固定距离。发现温度无关值r0 =8.7 Å。对潜在的量子力学机制的全面解释需要进一步的实验。
Besides the known energy levels of Eu3+at lattice sites of symmetryC2in Y2O3, some transitions of this ion at lattice sites of symmetryC3iin the same host crystal have been found and it was possible to construct the energy level scheme in part. Evidence for an energy transfer from Eu3+(C3i) to Eu3+(C2) is given, the strength of which is measured as a function of the Eu2O3concentration. The results lead to the assumption of a fixed distanceR0for the interaction responsible for the energy transfer. A temperature-independent value ofR0=8.7 Å was found. The full explanation of the underlying quantum mechanical mechanism requires further experiments.
