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

In order to design silicate glasses suitable as the host media for the Er 3+ ions we studied a role of divalent cations (magnesium, calcium and/or zinc) on the properties of the glasses. In this study we focused on comparing the glasses from the point of view of their spectroscopic properties and fe
The room temperature emission spectrum at about 2.7 lm corresponding to the laser transition 4 I 11/2 ! 4 I 13/2 in Er 3+ -doped nanoscaled transparent oxyfluoride glass-ceramic has been measured and stimulated emission cross-section for the transition has been calculated. The intensity of the trans
