Abstract

The significant applications of Er³⁺-doped fiber lasers in the infrared spectral region have generated considerable research interest. However, the relatively low radiative efficiency of Er³⁺ ions and the optimization of glass host matrices remain pivotal challenges constraining the advancement of NIR/MIR laser technologies. A set of tellurite glasses containing Er³⁺ concentrations varying from 3.0 to 9.0 mol% was synthesized in this study. The structural vibrations within the glass matrix were analyzed using Raman and infrared spectroscopy. The TBE3 glass samples exhibited notable emission cross sections, measured at 1.44 × 10^–20 cm² at 1.5 µm and 1.81 × 10^–20 cm² at 2.7 µm. These results collectively suggest that the highly Er³⁺-doped tellurite glass developed in this work is a promising high-doping material for infrared lasers and holds potential for applications in near-infrared (NIR) and mid-infrared (MIR) optical devices.

高掺Er3+在碲酸盐玻璃中的有效红外荧光

掺Er3+光纤激光器在红外光谱领域的重要应用引起了广泛的研究兴趣。然而，Er3+离子相对较低的辐射效率和玻璃基质的优化仍然是制约近红外/MIR激光技术发展的关键挑战。本研究合成了一套Er3+浓度为3.0 ~ 9.0 mol%的碲酸盐玻璃。利用拉曼光谱和红外光谱分析了玻璃基体内部的结构振动。TBE3玻璃样品具有显著的发射截面，在1.5µm处测量到1.44 × 10-20 cm2，在2.7µm处测量到1.81 × 10-20 cm2。这些结果共同表明，本研究开发的高Er3+掺杂碲酸盐玻璃是一种很有前途的红外激光器高掺杂材料，在近红外（NIR）和中红外（MIR）光学器件中具有应用潜力。

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
