Abstract

An investigation of fluoroindate glass and fiber co-doped with Yb/Er ions as a potential temperature sensor was assessed using the fluorescence intensity ratio (FIR) technique. Analysis of thermally coupled levels (TCLs-H and S), non-thermally coupled levels (non-TCLs-F and F), and their combination were examined. Additionally, the luminescent stability of the samples under constant NIR excitation using different density power at three different temperatures was carried out. The obtained values of absolute sensitivity (0.003 K-glass, 0.0019 K-glass fiber H → S transition) and relative sensitivity (2.05% K-glass, 1.64% K-glass fiber F → F transition), as well as high repeatability of the signal, indicate that this material could be used in temperature sensing applications.

摘要

采用荧光强度比（FIR）技术对掺Yb/Er离子的氟铟酸盐玻璃和光纤作为潜在温度传感器进行了研究。分析了热耦合能级（TCLs-H和S）、非热耦合能级（非TCLs-F和F）及其组合。此外，还研究了样品在三种不同温度下使用不同密度功率的恒定近红外激发下的发光稳定性。所获得的绝对灵敏度值（0.003 K-玻璃，0.0019 K-玻璃光纤H→S跃迁）和相对灵敏度值（2.05% K-玻璃，1.64% K-玻璃光纤F→F跃迁）以及信号的高重复性表明，这种材料可用于温度传感应用。
