Effects of alkaline-earth fluorides and OHa on spectroscopic properties of Yb3+ doped TeO2aZnOaB2O3 based glasses

New kinds of Yb2O3-doped boro-tellurite (TeO2aZnOaB2O3) based glasses were prepared by introducing alkaline-earth fluorides (MgF2, CaF2, SrF2, and BaF2). Their structural and spectroscopic properties were investigated by Raman and absorption spectra measurements. Dehydration ability of alkaline-eart...

Description
Summary:	New kinds of Yb2O3-doped boro-tellurite (TeO2aZnOaB2O3) based glasses were prepared by introducing alkaline-earth fluorides (MgF2, CaF2, SrF2, and BaF2). Their structural and spectroscopic properties were investigated by Raman and absorption spectra measurements. Dehydration ability of alkaline-earth fluorides was studied. The OHi, can have an obvious effect on fluorescence lifetime of Yb3+, when OHi, concentration is higher than NOH=4.66A1019 cma3. For TeO2aZnOaB2O3aBaF2 glass system, the peak values of integrated absorption and emission cross-sections achieve 7.44A104 pm3 and 1.416 pm2, respectively. It indicates that the Yb3+-doped boro-tellurite glasses containing alkaline-earth fluorides are potential materials for waveguide laser, and optical amplifier.
