| 摘 要： | 用高温熔融法制备了Er^3 单掺和Er^3 /Yb^3 双掺铋硼酸盐玻璃样品，测量了上述玻璃样品的吸收光谱，荧光光谱，荧光寿命以及红外透过率。对高浓度掺杂Er^3 的铋硼酸盐玻璃中的浓度猝灭现象作出了解释。分析了Er^3 ／Yb^3 双掺铋硼酸盐玻璃样品中Yb^3 离子对Er^3 离子的敏化过程。研究发现Er^3 ／Yb^3 双掺铋硼酸盐玻璃在1．5～1．6μm波段有宽达81nm的荧光半峰全宽。实验还发现在熔制过程中通入氧气对其荧光寿命和红外透过率都有明显的提高。由于该玻璃材料表现出较好的物化性能。因此该材料可望成为宽带光纤放大器的适宜的基质材料。

| Abstract: | Some bismuth borate glasses with Er3+-doped and Er3+/Yb3+ co-doped are fabricated by the technique of high-temperature melting. The absorption and fluorescence spectra, fluorescence lifetime and transmission in infrared range are measured. Explanation of concentration quenching in case of high level Er3+-doped the bismuth borate glasses is given. The sensitizing of Yb3+ to Er3+ in Er3+/Yb3+ co-doped bismuth borate glasses is discussed. It is found that the band around 1.5～1.6 μm in Er3+/Yb3+ co-doped bismuth borate glass reaches 81 nm and the fluorescence lifetime of Er3+ is enhanced obviously when the glass is treated with oxygen in melting process. In the meantime the glasses show favorable chemical and physical properties. It is expected to be a favorable candidate host for broadband amplifiers. |
