The glasses used in measurements are with a mol% composition of 70TeO2-9PbF2-190AlF3-10BaF2-1Er2O3. The s intensity parameters  the radiative rates  the branching ratios and the fluorescence lifetimes were calculated based upon the Judd-Ofelt theory and the experimental absorption spectrum. Under 980 nm excitation  efficient 530  544  and 665 nm upconversion emission are due to two-photon absorption processes.   Temperature dependence of structural and luminescent properties of Tb3+ doped YPO4 - art. no. 60300M 会议论文 2006 Di W.

According to the radiative lifetime obtained from the Judd-Ofelt parameters and the measured lifetime  the 1.5m quantum efficiency was calculated. The quenching effect of OH upon the lifetime of 1.5m emission was investigated. From the absorption sideband measurement of glass host  the value of optical band gap was estimated. The McCumber theory was used to calculate the stimulated emission cross-section and in approximate agreement with experimental one if the emission spectrum could be obtained accurately. The gain coefficient spectra were computed.   Energy upconversion in erbium doped oxyfluoride tellurite glass - art. no. 60291Y 会议论文 2006 Ren G. Z.; Chen B. J.; Wang X. J.; Yang Y. M.; Meng Q.
