Abstract A series of Er3+/Yb3+ co-doped fluorophosphate glasses with varying YbF3 concentration were prepared by a high temperature melt quenching technique. Absorption and emission cross-sections were determined by using the McCumber theory. The larger emission cross-section (9.86 × 10−21 cm2) and longer fluorescence lifetime (12.37 ms) were obtained for the 4I13/2 → 4I15/2 transition of ABS3Er4Yb glass. The sensitivity and temperature of the maximum sensitivity were evaluated by the fluorescence intensity ratio method from the measured upconversion spectra. The results were discussed and compared to the other reported glasses.

用于 NIR 发光和光学温度传感器应用的 Er 3+ /Yb 3+ 共掺杂氟磷酸盐玻璃的光谱特性

摘要 采用高温熔体淬火技术制备了一系列不同YbF3浓度的Er3+/Yb3+共掺杂氟磷酸盐玻璃。吸收和发射截面是通过使用麦康伯理论确定的。ABS3Er4Yb 玻璃的 4I13/2 → 4I15/2 转变获得了更大的发射截面 (9.86 × 10−21 cm2) 和更长的荧光寿命 (12.37 ms)。最大灵敏度的灵敏度和温度通过荧光强度比法从测得的上转换光谱进行评估。讨论了结果并与其他报道的眼镜进行了比较。
