Abstract Improving the luminescence efficiency of rare earth ions in optical solids has been an important and challenging area of study in recent decades. In this paper, we report the enhanced luminescence performance of Er3+ ions in optical glasses with a stable glass forming ability, owing to the hybrid structure evolution by controlling the amount of chloride. The evolution of TeO4→TeO3+δ→TeO3 and the appearance of the ZnCl4 unit are evident in the Raman and XPS results, which is significantly beneficial to the visible and 1.5 and 2.7 μm emissions of Er3+ ions. Therefore, this type of amorphous solid, including an oxychloride hybrid structure, challenges the traditional concept of glass formation. Additionally, it may be a promising candidate as a gain medium for rare-earth-doped solid-state lasers, thereby providing a method for studying the effect of the glass structure on the activated ion luminescence.

通过使用氯化物的混合结构波动控制在氧化物无定形固体中具有优异的发光性能

摘要 近几十年来，提高光学固体中稀土离子的发光效率一直是一个重要且具有挑战性的研究领域。在本文中，我们报告了具有稳定玻璃形成能力的光学玻璃中 Er3+ 离子的增强发光性能，这是由于通过控制氯化物的量来进行混合结构演变。TeO4→TeO3+δ→TeO3 的演变和 ZnCl4 单元的出现在拉曼和 XPS 结果中很明显，这对 Er3+ 离子的可见光和 1.5 和 2.7 μm 发射非常有利。因此，这种类型的无定形固体，包括氯氧化物杂化结构，挑战了玻璃形成的传统概念。此外，它可能是稀土掺杂固态激光器的增益介质的有希望的候选者，
