Abstract

Ce3+ or Tb3+ ions activated lithium-barium-gadolinium-aluminosilicate oxyfluoride glasses have been prepared. The transmission, emission and excitation spectra were measured. It has been found that those Ce3+ or Tb3+-doped lithium-barium-gadolinium-aluminosilicate oxyfluoride glasses exhibit good UV-excited luminescence. Energy transfer process from Gd3+ ion to Ce3+ or Tb3+ ion is indicated.
