Abstract A compositional adjusting method called the mixed former effect is proposed to improve effectively optical properties such as emission cross section, the fluorescence full width at half maximum (FWHM) and the lifetime of the 4I13/2 level of Er-doped glass. A kind of Er-doped bismuth-based glass illustrated high emission cross section (σpe = 0.66-0.90pm2), large fluorescence FWHM (68-85 nm), and relative long lifetime of the 4I13/2 level (τm = 1.6-4.3ms) by this method. Comparison of spectroscopic parameters shows that bismuth-based glass is much better for broadband amplifier than other glass hosts.
