Abstract: The bismuth glasses with Er3+ and Er3+/Yb3+ codoped were fabricated by the technique of hightemperature melting. The absorption and fluorescence spectra, fluorescence lifetime and FWHM were measured. The explanation of concentration quenching in case of high level Er3＋doped the bismuth glasses is given. The sensitizing of Yb3＋ to Er3＋ in Er3＋/Yb3＋ codoped bismuth glasses is discussed. The explanation of the influence on absorption and fluorescence spectra, fluorescence lifetime and FWHM in case of the change of Er3+ or Yb3+ in bismuth glasses with Er3+/Yb3+ codoped is given. It is found that the change of Er3+ content has obviously influenced the fluorescence lifetime and FWHM while the change of Yb3+ content has remarkably influenced the absorption and fluorescence intensity. The band at around 1.54 μm in Er3+/Yb3+ codoped bismuth glass reaches 76 nm and the fluorescence lifetime is 0.55 ms.
