硫系玻璃 微晶玻璃 稀土离子 过渡金属离子 中红外发光 Chalcogenide glass Glass ceramics Rare earth ions Transition metal ions Mid infrared emission
摘要
回顾了近年来关于稀土或过渡金属离子掺杂的硫系发光微晶玻璃的研究进展.深入讨论了稀土离子在硫系微晶玻璃中的微观分布对其发光性能的影响,以及不同稀土离子与晶体场之间相互作用的机制.总结和分析了近两年提出的一种新型硫系微晶玻璃——过渡金属离子激活的硫系微晶玻璃.通过可控晶化和晶体场调控,已经在硫系微晶玻璃实现了较强的Cr2+: 1.8~2.8 μm以及Co2+: 2.5~4.5 μm中红外超宽带输出.梳理了影响和制约硫系微晶玻璃在中红外光子器件功能化方面的关键问题,为今后此类研究提供一种思路.
Abstract
Recent research progress of rare-earth or transition metal ions doped luminescent chalcogenide (ChG) glass ceramics (GCs) was reviewed. Correlation between emission properties and microscopic distribution of rare earth ions in ChG GCs, and the underlying mechanisms of the interaction between different rare earth ions and crystal field were discussed comprehensively. Moreover, the key features of novel transition metal ions activated ChG GCs developed in the past two years were also summarized. Strong ultrabroadband of Cr2+: 1.8~2.8 μm, and Co2+: 2.5~4.5 μm mid infrared emissions were realized with careful compositional design and controlled crystallization. Our short review summarized the key issues that can influence and restrict the functionalization of ChG GCs, offering a guideline for future research direction on this topic.
