摘要：
A new long afterglow phosphor Y2O2S:Ti4+, Mg2+ Co-doped with Gd3+ and Lu3+ was synthesized by solid-state reaction in inert gas ambient. Its properties were systematically analyzed by X-ray diffraction (XRD), luminescence spectra, afterglow decay curves and thermoluminescence (TL) spectra. it was found that the long afterglow performance Of Y2O2S:Ti4+, Mg2+ such as brightness and persistent time was largely improved when co-cloped with Cd3+ and Lu3+. By analyzing the TL curve the activation energy E were calculated to be 0.64 eV for 388 K peak and 0.98 eV for 508 K peak. and the trap intensity related to 388 K peak is much stronger than that related to 508 K peak. The mechanism of the long afterglow was also discussed in this paper. (C) 2009 Elsevier B.V. All rights reserved.
