  • The bismuth glasses with Er3+ and Er3+/Yb3+ codoped were fabricated by the technique of hightemperature 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+ codoped 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+ codoped 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+ codoped bismuth glass reaches 76 nm and the fluorescence lifetime is 0.55 ms.

Abstract: The bismuth glasses with Er3+ and Er3+/Yb3+ codoped were fabricated by the technique of hightemperature 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+ codoped 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+ codoped 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+ codoped bismuth glass reaches 76 nm and the fluorescence lifetime is 0.55 ms.
