Influences of Tm2O3 Doping Concentration on Thermal Stability and Spectroscopic Properties of Germanate Glass
The Tm2O3-doped 55GeO2-15PbO-5PbF2-10BaO-10ZnO-5K2O germanate glass is fabricated by using the high temperature melt-quenching method. The thermal stability and structures of this glass are measured, and the thermal stability coefficient of this glass is greater than 180 ℃. The hydroxyl content of this glass is measured by a infrared spectroscopy and the hydroxyl absorption coefficient is less than 0.51 cm -1. The absorption and fluorescence spectra are obtained under different Tm2O3 doping concentrations. The research results show that the cross-relaxation rate increases with the increase of Tm2O3 mass fraction. When the mass fraction of Tm2O3 is 5%, the fluorescence intensity at a wavelength of 1880 nm reaches the maximum, and the peak emission cross section of 3F4→ 3H6 energy transition is up to 5.84×10 -21 cm 2.
