Abstract

GdF3 nanocrystals doped with Eu3+ ions in oxyfluoride glass ceramics were prepared by a solgel method. The structural properties were examined by x-ray diffraction measurements. The effects of gadolinium codoping on europium emission in the prepared solgel glasses and glass ceramics have been studied. The emission bands originating from the D05 state of Eu3+ ions are enhanced under excitation of Gd3+ ions by 273 nm line. The electric dipole D05F27 transitions were dominant in the samples before heat treatment, whereas magnetic dipole D05F17 transitions had a higher probability in the samples after annealing. The luminescence lifetime for the D05 level of Eu3+ ions in the samples after excitation at 273 nm is long lived in comparison to excitation at 393 nm and increased to 190%. Energy transfer from Gd3+ to Eu3+ was observed.
