用紫外光和真空紫外光同步辐射测量了LiYF4中Ce3+、Pr3+和Nd3+的4fN和4fN−1 5d组态跃迁的激发光谱。观察到零声子线和振动带。通过考虑5d电子的晶场相互作用和自旋轨道相互作用，以及4f和5d电子之间的库仑相互作用，扩展了已建立的4fN组态模型，再现了能级和跃迁强度。
Excitation spectra of transitions between the 4 f N and 4 f N− 1 5 d configurations of Ce 3+, Pr 3+, and Nd 3+ in LiYF 4 have been measured using UV and VUV synchrotron radiation. Both zero-phonon lines and vibronic bands are observed. The energy levels and transitions intensities are reproduced by a theoretical model that extends established models for the 4 f N configuration by including crystal-field and spin-orbit interactions for the 5 d electron and the Coulomb interaction between the 4 f and 5 d electrons.
