摘要

A compositional adjusting method called the mixed former effect is proposed to improve effectively opticalproperties such as the emission cross section, the fluorescence full width at half maximum (FWHM) and thelifetime of the 4I13/2 level of Er-doped glass. A kind of Er-doped bismuth-based glass illustrated high emissioncross section (σep = 0.66 - 0.90pm2), large fluorescence FWHM (68-85nm), and relatively long lifetime of the4 I1s/2 level (Tm = 1.6-4.3 ms) using this method. A comparison of spectroscopic parameters shows that bismuth-based glass is much better for broadband amplifiers than other glass hosts.
