摘要

本文采用高温熔融法制备了新型Er3+单掺和Er3+/Yb3+共掺的TeO2-Bi2O3-SiO2-B2O3玻璃，测试和分析了样品的吸收光谱、发射光谱以及Er3+/Yb3+共掺杂样品的发射光谱和荧光寿命。计算出了玻璃的J-O强度系数Ωt(t=2

6)；系统讨论了Er3+/Yb3+共掺杂样品在808nm激光激发下，Yb3+与Er3+近红外发射强度比的变化情况及Er3+→Yb3+的反向能量传递机理。结果表明：Er3+单掺玻璃系统在1.53μm附近的最大发射带宽可达90nm；适量的Yb3+引入到掺Er3+玻璃中，可有效地减小Er3+:4I13/2能级的消布居速率，提高Er3+:4I13/2→4I15/2的发射强度和Er3+：4I13/2能级的寿命。

Abstract

Erbium-doped fiber amplifier (EDFA)

utilizing the emission transition 4I13/2→4I15/2 of Er3+

is a key element of the 1.5μm window telecommunication system. In recent year

in order to raise amplifier gain parameters

many solutions

such as Er3+/Yb3+

Er3+/Eu3+

Er3+/Sm3+-doped

were introduced. In this paper

novel Er3+doped and Er3+/Yb3+co-doped TeO2-Bi2O3-SiO2-B2O3 glasses were prepared by high-temperature melt-quenching method. The absorption spectra and emission spectra of Er3+- doped glasses

the emission spectra and lifetimes of Er3+/Yb3+co-doped glasses were measured and investigated. The intensity parameters Ωt (t=2

6) were calculated by using the theory of Judd-Ofelt. Under 808nm semiconductor laser excitation

the infrared emission intensity ratio of Yb3+ ions to Er3+ ions and mechanism of counter energy transfer were discussed in Er3+/ Yb3+co-doped glasses. The results indicate that a maximum value of full width half maximum (FWHM) of 1.53μm infrared emission spectra is 90 nm in Er3+-doped glasses

and the suitable content of Yb3+ ions is helpful for decrease disappearing population velocity of Er3+:4I13/2 level

increase emission intensity of Er3+:4I13/2→4I15/2 transition and lifetime of Er3+:4I13/2 level.
