Er3+单掺和Er3+/Yb3+共掺碲酸盐玻璃的光谱性质及能量传递
Spectroscopic Properties and Energy Transfer of Er3+-doped and Er3 +/Yb3 + Co-doped Tellurite Glasses
摘要
Abstract
Erbium-doped fiber amplifier (EDFA) , utilizing the emission transition 4I3/2→4I15/2 of Er3+ , is akey element of the 1. 5 μm window telecommunication system. In recent years, 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 glass were prepared by high-temperature melt-quenching method. The absorption spectra and emission spectra of Er3 + - doped glass, the emission spectra and lifetimes of Er3+ /Yb3+ co-doped glass were measured and investigated. The intensity parameters Ω,(t =2,4,6) were calculated by using the theory of Judd-Ofelt. Under 808 nm 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 glass. The results indicate that a maximum value of full width half maximum ( FWHM) of 1. 53 μm infrared emission spectra is 90 nm in Er3 + -doped glasses, and the suitable content of Yb3+ ions is helpful for decreasing the disappearing population velocity of Er3+ :4I13/2 level, increasing the emission intensity of Er3+ :4I13/2-→4I15/2 transition and lifetime of Er3+ ;4I13/2 level.关键词
