摘要/Abstract

摘要： 制备了掺Er³⁺氟铅硅酸盐玻璃,研究了玻璃的物理性质、热稳定性、吸收光谱、荧光光谱和荧光寿命.应用McCumber理论,计算了能级4I_13/2→⁴I_15/2跃迁的吸收和受激发射截面.结果表明:以PbF₂等分子替代:PbO含量,样品密度、折射率、热稳定性、吸收截面和受激发射截面降低,但荧光半高宽和荧光寿命增加.对Er³⁺离子在不同玻璃基质中带宽特性的比较发现,Er³⁺掺杂50SiO₂-50PbF2玻璃的带宽特性与碲酸盐和铋酸盐玻璃相当,大于磷酸盐,锗酸盐和硅酸盐玻璃,表明掺Er3+氟铅硅酸盐玻璃可作为宽带光纤放大器的基质材料.

Abstract: Er³⁺-doped fluoride lead silicate glasses were fabricated. The physical properties, thermal properties, absorption
spectra, fluorescence spectra and fluorescence lifetimes of the samples were investigated. The absorption and stimulated
emission cross-sections of ⁴I_13/2→⁴I_15/2 transition of the samples were calculated by McCumber theory.
The results show that densities, refractive indices, thermal stability, absorption and stimulated emission cross-sections of
the samples decrease, but the fluorescence full width at half max maximum and fluorescence lifetimes of the ⁴I_13/2
level of Er³⁺ increase. Compared with other glass hosts, the gain bandwidth property of Er³⁺-doped 50SiO₂-50PbF₂
glass is close to those of tellurite and bismuth glasses, and has advantage over those of silicate, phosphate and germante lasses, which shows that Er³⁺-doped fluoride lead silicate glasses can be as host materials for broadband optical amplifier.

Key words: fluoride lead silicate glasses, spectral properties, optical fiber amplifier, Er³⁺ ion
