Abstract
The luminescence properties of Ce3+ ions in magnesium fluoroborates, Mg3BO3 F3 and Mg2BO3F, upon X-ray and synchrotron radiation excitation are reporte d and discussed. VUV excitation spectra of Mg3BO3F3 : Ce3+ can be reasonabl y explained by taking into account several factors, such as the electronic structure of Mg3BO3F3 and energy loss mechanisms. It is suggested that the luminescence behavior of Ce3+ is influenced by the presence of F- vacancies in the lattice. (C) 2001 Elsevier Science Ltd. All rights reserved.
