Abstract

This work reports on the fabrication and analysis of near-infrared and mid-infrared luminescence spectra and their decays in fluoroindate glasses co-doped with Yb/Ho. The attention has been paid to the analysis of the Yb→ Ho energy transfer processed ions in fluoroindate glasses pumped by 976 nm laser diode. The most effective sensitization for 2 μm luminescence has been obtained in glass co-doped with 0.8YbF/1.6HoF. Further study in the mid-infrared spectral range (2.85 μm) showed that the maximum emission intensity has been obtained in fluoroindate glass co-doped with 0.1YbF/1.4HoF. The obtained efficiency of Yb→ Ho energy transfer was calculated to be up to 61% (0.8YbF/1.6HoF), which confirms the possibility of obtaining an efficient glass or glass fiber infrared source for a MID-infrared (MID-IR) sensing application.

摘要

这项工作报道了掺镱/钬氟铟酸盐玻璃中近红外和中红外发光光谱的制备与分析及其衰减情况。研究重点是对976纳米激光二极管泵浦的氟铟酸盐玻璃中镱→钬能量转移过程离子的分析。在掺0.8YbF/1.6HoF的玻璃中获得了对2微米发光最有效的敏化效果。在中红外光谱范围（2.85微米）的进一步研究表明，在掺0.1YbF/1.4HoF的氟铟酸盐玻璃中获得了最大发射强度。计算得出镱→钬能量转移的效率高达61%（0.8YbF/1.6HoF），这证实了获得用于中红外（MID-IR）传感应用的高效玻璃或玻璃纤维红外源的可能性。
