Abstract:The Eu2+ and Mn2+ codoped 50SiO2–17Al2O3–23MgF2–10NaF glasses and glass–ceramics were prepared and their luminescence properties were investigated. The red emission intensity of Mn2+ in the Eu2+ and Mn2+ codoped glass was about five times stronger than that in the Mn2+ doped glass, which could be attributed to energy transfer from Eu2+ to Mn2+. The energy transfer mechanism from Eu2+ to Mn2+ in glasses was determined to be a dipole-quadrupole interaction. The luminescence intensity of the glass–ceramics was stronger than that of the glass because some Eu2+ and Mn2+ ions entered lower phonon energy environment of MgF2 nanocrystals in the glass–ceramics.
