The Bi/Sn-doped aluminosilicate glass samples were prepared using a melting-quenching method and their near-infrared (NIR) emission properties were studied. An ultra-broadband NIR emission ranging from 950 nm to 1600 nm was observed in all samples under 480 nm excitation, which covered the whole fiber low-loss window. The NIR emission spectrum showed that the maximum emission peak was about 1206 nm and the full width at half maximum (FWHM) was about 220 nm. Furthermore, the NIR emission intensity strongly depends on the composition of the glass, which can be optimized by modulating the glass composition. The Bi and Bi ions were the NIR luminescence source of the glass samples in this paper. The Bi/Sn-doped aluminosilicate glass has the potential to become a new type of core fiber material and to be applied to optical fiber amplifiers (OFAs), based on its excellent performance in ultra-broadband NIR emission.
采用熔融淬火法制备了铋/锡掺杂的铝硅酸盐玻璃样品，并对其近红外（NIR）发射特性进行了研究。在480nm激发下，所有样品均观察到950nm至1600nm的超宽带近红外发射，覆盖了整个光纤低损耗窗口。近红外发射光谱表明，最大发射峰约为1206nm，半高宽（FWHM）约为220nm。此外，近红外发射强度强烈依赖于玻璃的组成，可通过调节玻璃组成进行优化。铋和铋离子是本文玻璃样品的近红外发光源。铋/锡掺杂的铝硅酸盐玻璃基于其在超宽带近红外发射方面的优异性能，有潜力成为一种新型的纤芯光纤材料，并应用于光纤放大器（OFA）。
