摘要：

Site-selective excitation of Eu+3 beta"-alumina into the 5D0 level (568-579 nm) shows that the europium ion occupies at least two types of site distributions. The first distribution occurs at the higher energy of the tuning range and has site symmetry C3-upsilon or C3. It corresponds to the crystallographic Beevers-Ross position. The other site distribution is observed at lower energy and is associated with the mid-oxygen crystallographic position (site symmetry: C2h). We also show that interpretation of the site-selective spectroscopy of Eu+3 beta"-alumina must take into account the occurrence of site-to-site energy transfer linked to vibronic coupling phenomena.
