✦ Synopsis

We have prepared polycrystalline alloys x(ErF 3 ):(100 À x)(PbF 2 ), x = 1, 10. A comparison of their low temperature absorption and emission spectra with the respective spectra of transparent oxyfluoride glass-ceramics, 32(SiO 2 )9(AlO 1.5 )31.5(CdF 2 )18.5(PbF 2 )-5.5(ZnF 2 ):3.5(ErF 3 ) mol%, indicates that the nano-crystalline phase in this glass-ceramic is Er 3+ -doped PbF 2 .

The fluorine losses during synthesis of Er 3+ doped transparent glasses in the SiO 2 -PbO-PbF 2 system were investigated. The final fluorine contents of the glasses were detected by using a fluorine ion selective electrode. The results show that high fluorine losses are occured in the normal prepara
