摘要

可调宽带近红外发光材料作为红外光源和可调谐光纤激光器核心组件，在高容量光纤通信、成像和遥感等现代技术中发挥着至关重要的作用。本文研究了碲掺杂钙-铝-锗酸盐玻璃的宽带近红外发光性能调控方案及其机理。通过引入碳构建还原气氛，还原TeO

原料为碲原子；再优化CaO、Al

含量，调整碲掺杂钙-铝-锗酸盐玻璃中碲拓扑笼的结构和大小，稳定并调控碲团簇发光中心，实现高效且可调谐的宽带近红外发光。最后通过改变TeO

掺杂含量，提供可形成团簇的合适含量碲源，进一步增强碲近红外发光，并揭示了碲近红外发光性能调控机理。本研究为未来宽带、高效、可调谐的近红外发光材料设计提供了重要指导，推进了其在宽带光放大器和可调谐激光器中的应用。

Abstract

Tunable broadband near-infrared(NIR)-emitting materials play a crucial role as NIR light sources and tunable fiber lasers in modern technologies such as high-capacity telecommunication

imaging

and remote sensing. In this work

we report the control scheme and mechanism of the broadband near-infrared luminescence properties in the tellurium-doped calcium-aluminum-germanate glass. By introducing carbon to construct a reducing atmosphere

the raw material TeO

is reduced to tellurium element. Through optimizing CaO and Al

content

the configurations and size of topological cages in tellurium doped calcium-aluminum-germanate glass were adjusted to stabilize and tailor tellurium clusters

enabling tunable NIR emission. Furthermore

adjusting the content of TeO

provides optimal tellurium source to form clusters

and thus enhancing tellurium NIR luminescence. The regulation mechanism of tellurium NIR luminescence performance in the calcium-aluminum-germanate glass is clarified. This work provides important guidance for the design of broadband

efficient and tunable NIR luminescent materials

promoting their practical application in broadband optical amplifiers and tunable lasers.
