Optical transitions of Tm3+ in oxyfluoride glasses and compositional and thermal effect on upconversion luminescence of Tm3+/Yb3+-codoped oxyfluoride glasses.
Optical properties of Tm(3+)-doped SiO2-BaF2-ZnF2 glasses have been investigated on the basis of the Judd-Ofelt theory. Judd-Ofelt intensity parameters, radiative transition probabilities, fluorescence branching ratios and radiative lifetimes have been calculated for different glass compositions. Upconversion emissions were observed in Tm(3+)/Yb(3+)-codoped SiO2-BaF2-ZnF2 glasses under 980 nm excitation. The effects of composition, concentration of the doping ions, temperature, and excitation pump power on the upconversion emissions were also systematically studied.

[Studies on the properties of energy upconversion of the rare earth ErYb and HoYb in the oxyfluoride glass].
Er and Yb, Ho and Yb codoped in the oxyfluoride were burnt on in the specific temperature, and got two kinds of samples. Using 930 nm as an exciting light, the emitting fluorescent spectra of two kinds of the samples were measured, and observed the red band and green band fluorescent spectra, respectively. According to the detected absorption spectra of Er2O3, Ho2O3, Yb2O3 and the rule of energy jump, the mechanism and the properties of the energy upconversion of two kinds of the samples were explained. As can be seen, energy upconversion properties were determined mainly by the absorbtion spectra of Er2O3, Yb2O3. Energy upconversion efficiency were determined by excitative photons.
