摘要
Ce3+ and Tb3+ ions are important activators for various phosphors, but no detailed study has been performed on SrLiB9O15 crystal. Ce3+- and Ce3+/ Tb3+-doped SrLiB9O15 phosphors were synthesized by using a standard high temperature solid-state technique. The phase purity and optical properties of the prepared samples are investigated by XRD, excitation and emission spectra. The unusual luminescence properties of Ce3+ activator, the Ce3+ site occupying and Ce3+ -> Tb3+ energy transfer behavior are discussed. (C) 2014 Elsevier B.V. All rights reserved.
