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
