“…Taken T8 phosphate glass as the core and K9 commercial silicate glass as the clad, silicate-clad Tb 3+ doped phosphate glass core glass fiber was successfully drawn according to our previous work. [49] The SEM image of the fiber cross section shown in Figure 7a displays the high-quality core/clad interface with the inner and outer diameter estimated to be 25 and 194 μm, respectively. EDS mapping of different elements depicted in Figure 7b illustrates that Si element from K9 glass mostly distributes in the clad area, while other elements that are rich in T8 phosphate glass mainly locate in the core area, which meets our expectation.…”

Though widely applied in light-emitting diode (LED) lighting and X-ray detection, respectively, rare-earth ions doped phosphor and scintillating single crystals still face many challenges in practicalities, like aging of package material and difficulty to construct tiny array structure. Using phosphate glass as the host is quite beneficial for solving these problems while enabling distinguished luminescence. Therefore, Eu 3+ and Tb 3+ doped phosphate glasses which, respectively, show strong red/green emissions are researched. Superior thermal stabilities (78.69% and 89.35% emission intensities remain at 150 °C) and high internal quantum efficiencies (87.3% and 68.6%) are found to guarantee the excellent photoluminescence performances. The brilliant X-ray excited luminescence properties are demonstrated by general 19.49% and 34.74% integrated emission intensities of that of commercial Bi 4 Ge 3 O 12 single crystal scintillator with the change of X-ray power. Meanwhile, Tb 3+ doped scintillating fiber is drawn. Finally, excited by 380 nm LED, color manipulation and white light generation are achieved in LEDs with a structure of stacked emitting layers (mainly Eu 3+ and Tb 3+ doped phosphate glasses). Many of the as-constructed white LED's performance parameters are much better than the commercial white LED. These results show that Eu 3+ and Tb 3+ doped phosphate glasses possess promising potential in LED lighting and X-ray detections.

“…Notice that the Stokes limit (λ p /λ s ), is defined as the ratio of the pump wavelength (λ p ), to signal or laser wavelength (λ s ). Recently, Dy−doped multi-component phosphate glass was examined and showed a strong yellow emission which was due to the high asymmetry and covalency of the local field and the high phonon energy [20]. In that work, Dy−doped multi-component phosphate core glass fiber was successfully drawn by using a rod-in-tube method.…”

In this paper, a Forward Time Centered Space (FTCS) method and an analytical method have been developed to fully investigate the 4 F 9/2 to 6 H 13/2 lasing transition of a dysprosium Dy−doped ZBLAN fiber which provides the potential of highly efficient yellow laser direct generation. This light source is of significant interest for treating diabetic retinopathy, which can cause blindness. The developed method's validity is confirmed through the comparison with experimental investigations of Dy−doped ZBLAN fiber lasers in other valid research. A full analysis of Dy−doped fiber laser including the population of the energy levels, power evolution of the laser and pump signals, amplified spontaneous emission (ASE), excited state absorption (ESA), radiative and non-radiative time transition rates are presented. The developed numerical method gives a better understanding of the impact of ASE and ESA on laser performance. The influence of overlap integrals, output mirror reflectivity, and active fiber length on laser performance is investigated. The optimization criteria based on the different robust configurations of laser cavities are found which predict the slope efficiencies higher than half of the Stokes limit.
