摘要/Abstract

摘要： 测得了Er³⁺离子在铋酸盐玻璃系列(50～75)Bi₂O₃-(20～45)B₂O₃-5Na₂O,70Bi₂O₃-(17～25)B₂O₃-xZrF₄-5Na₂O,70Bi₂O₃-(0～25)B₂O₃-(0～25)SiO₂-5Na₂O中的吸收光谱、荧光光谱及⁴I_13/2能级荧光寿命。提出并研究了Er³⁺离子光谱性质的混合形成体效应,结果表明Er³⁺离子在铋酸盐玻璃中通过混合形成体效应可以获得较大的有效线宽(△λ_eff=62～80nm)、较高的受激发射截面(σ_e=0.76～0.84×10^-20cm^~2)、较宽的荧光半高宽(FWHM=55～80nm)以及较长的荧光寿命(T_m=1.6～4.3ms),说明掺Er³⁺铋酸盐玻璃是光纤放大器实现宽带和高增益放大较为理想的基质材料。

Abstract: Er³⁺-doped bismuth-based glasses with compositions of (50～75)Bi₂O₃-(20～45)B₂O₃-5Na₂O, 70Bi₂O₃-(17～25)B₂O₃-xZrF₄-5Na₂O, 70Bi₂O₃-(0～25)B₂O₃-(0～25)SiO₂-5Na₂O were prepared. The absorption spectra, emission spectra and lifetime
of ⁴I_13/2 level of Er³⁺ ion were measured. The mixed former effect was mentioned firstly and its effects on spectroscopic properties of Er³⁺
ion were investigated. The results indicate that an increase of effective absorption bandwidth, emission cross section, FWHM, and relatively higher
lifetime could be obtained in the bismuth-based glasses through mixed former effects. All these data suggest that Er³⁺ doped bismuth-based glass is
a good candidate host material for optical amplifiers to realize broadband and high gain amplification.

Key words: mixed former effect, bismuth-based glass, spectroscopy, Er³⁺ ion
