SrAl2O4: Eu, Dy addied with fluorine was prepared by solid state reaction method. The X-Ray diffraction (XRD) results showed that all of the prepared samples exhibits single-phase SrAl2O4, but slight different phase was observed with increasing fluorine content. The activation energy of the trap level measured by thermoluminescence increased with addition of fluorine. We found that addition of small amount of fluorine had effects of increasing mechanoluminescence and long-lasting phosphoresence intensities. These results were explained by the increased activation energy and the increasing crystalline size.
