作者报道了Bi5+掺杂的GeO2-Al2O3-Na2O、GeO2-Al2O3-BaO和GeO2-Al2O3-Y2O3玻璃在O到S波段的近红外宽带发射。超宽带特性归因于Bi5+离子的发射。玻璃光学特性的差异是由于引入了钇和钡而影响了Bi5+。由于在GeO2-Al2O3-Bi2O3体系中，钇和钡的结合为Bi5+的形成提供了良好的环境，因此钇和钡的结合导致了吸收边的红移以及Bi5+浓度的增强。(c) 2006年美国物理研究所。
The authors report on near infrared broadband emission with a wavelength ranging from O to S telecommunication bands in Bi5+-doped GeO2-Al2O3-Na2O, GeO2-Al2O3-BaO, and GeO2-Al2O3-Y2O3 glasses. The superbroadband character is ascribed to the emission of Bi5+ ions. The differences among the optical characters of the glasses are due to the Bi5+ affected by the introduction of yttrium and barium. As the integration of yttrium and barium into GeO2-Al2O3-Bi2O3 system would offer a preferable environment for the formation of Bi5+, the integration of yttrium and barium leads to the redshift of absorption edges as well as the accentuation of Bi5+ concentration.
