摘要/Abstract

摘要： 通过真空熔融淬冷法制备了不同浓度Tm³⁺/Ho³⁺离子共掺的70GeS₂-20In₂S₃-10CsI玻璃样品, 分析了样品的热稳定性及拉曼光谱, 测试了样品的吸收光谱以及808 nm激光泵浦下Ho³⁺: ⁵I₇→⁵I₈辐射跃迁对应的2.00 μm荧光光谱特性. 结果表明: Tm³⁺离子掺杂浓度为0.25mol%时, 随着Ho³⁺离子掺杂浓度从0.05mol%增加到0.125mol%, Tm³⁺离子在1.86 μm的发光强度逐渐减弱, Ho³⁺离子2.00 μm荧光明显增强, 表明Tm³⁺/Ho³⁺离子之间存在有效的能量转移.

Abstract: 2 μm laser has many potential applications on the medical surgery, laser radar, and pollution monitoring etc. Tm³⁺ and Ho³⁺ ions co-doped 70GeS₂-20In₂S₃-10CsI chalcohalide glasses were synthesized by vacuumed melting- quenching technique. The DSC curves and Raman spectra showed that these glasses had good thermal stability and low phonon energy, respectively. The absorption and emission characteristics were evaluated with an emphasis on the 2.00 μm fluorescence from Ho³⁺: ⁵I₇→⁵I₈ transition. Under 808 nm excitation, the infrared emission bands extending from 1.80 μm to 2.10 μm can be seen on the emission spectra of the Tm³⁺ and Ho³⁺ ions co-doped glasses. This broad emission was consisted of two emission bands centered at 1.86 and 2.00 μm, corresponding to the optical transitions Tm³⁺:³F₄→³F₅ and Ho³⁺:⁵I₇→⁵I₈, respectively. At fixed Tm³⁺ ions concentration, the intensity of 2.00 μm emission increased with Ho³⁺ ions concentration increasing from 0.05mol% to 0.125mol%. The enhanced emission of Ho³⁺ ions gives another route to obtain the 2.00 μm infrared laser.

Key words: Tm³⁺/Ho³⁺ co-doped, chalcogenide glass, energy transfer
