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.   Rare-earth doped tungsten tellurite glasses and waveguides: Fabrication and characterization (EI CONFERENCE) 会议论文  OAI收割 Physics of Non-Crystalline Solids 10, October 15, 2004 - October 15, 2004, Parma, Italy 作者:  Chen B.;  Chen B. 收藏  |  浏览/下载：24/0  |  提交时间：2013/03/25 Tungsten tellurite glasses doped with Er3+  Tm3+  Pr3+  and Ho3+ ions were prepared by melt quenching. The glass matrix was the same for all types of glasses and had a high sodium content in order to allow the fabrication of waveguides using an ion-exchange technique. The absorption spectra of the glasses were measured and the Judd-Ofelt parameters q were obtained from the experimental oscillator strengths of the f &rarr f transitions. Er3+ doped glasses showed a very high quantum efficiency when comparing the calculated radiative decay time with the measured lifetime of the 4I 13/2 metastable level. Ag+ Na+ ion-exchanged planar waveguides were successfully obtained in all types of glasses and characterized by the prism coupling technique. It turned out that the diffusion constant values are very similar for glasses containing different rare-earth ions with the same concentration  while  at least for the Er 3+ doped ones  the diffusion constant changes with the ions concentration. 2004 Elsevier B.V.
