摘要：

Optical spectroscopy of Eu2+ ions in the conduction region of beta"-alumina is carried out following excitation with different wavelengths. The analysis of both the time-resolved spectra and the luminescence lifetimes suggests the occupation of two different manifolds of sites for Eu2+ ions inside the crystal lattice. The defective nature of the conduction plane of beta"-alumina is reflected by the strongly disordered distribution of the crystal fields.
