    摘要:

    采用传统高温熔融法制备了Bi/Yb3 共掺杂锗酸盐玻璃,通过测试吸收光谱、近红外光谱和荧光衰减寿命,研究了玻璃样品的近红外发光性质。在980nm 或808 nm 激光激发下,均能同时观察到Yb3 和Bi离子的近红外发光,这一结果表明,Yb3 离子与Bi离子之间存在相互能量传递。随着Yb3 离子浓度的增加,玻璃基质的光学碱度和Yb3 离子到 Bi 离子的能量传递效率均增加,讨论了能量传递效率的提高对Bi离子发光的增强作用与光学碱度增加对Bi离子发光的削弱作用的竞争影响机制,获得了Bi/Yb3 近红外发光的机理。

    Abstract:

    Bi/Yb3 co-doped germanate glasses were prepared by conventional melting-quenching technique. Near infrared (NIR) luminescence properties in Bi/Yb3 co-doped germanate glasses were investigated by the absorption spectrum, NIR luminescence spectra, and fluorescence lifetime measurement, respectively. NIR luminescence of both Yb3 and Bi ions was observed simultaneously, either under 980 or 808 nm excitation LD. The results show that ET process existed between Bi-related NIR emission centre and Yb3 ions. With the increasing in Yb3 ions concentration, both ET efficiency from Yb3 ions to Bi ion and optical basicity of glass matrix are increased. The competitive effect of enhancing by the ET process and weakening by optical basicity on NIR luminescence property of Bi ions is investigated.
