%X High phonon energy oxides of WO3, SiO2 and B2O3 were introduced into the Er3+/Ce3+ co-doped tellurite glass (TeO2-Bi2O3-TiO2) with low phonon energy, respectively. The absorption spectra in the wavelength region of 400–1700 nm, fluorescence spectra of 1.53μm band, fluorescence lifetimes of Er3+ and Raman spectra of the glasses were measured. The spectral parameters of Er3+ were calculated with the help of McCumber theory. It is shown that the energy transfer process between Er3+ and Ce3+ becomes more effectively when introducing the high phonon energy oxide, and the 1.53μm band fluorescence emission corresponding to Er3+:4I13/2→4I15/2 transition enhances accordingly due to the increased population of Er3+ in the 4I13/2 level. Meanwhile, the fluorescence width at half magnitude (FWHM) and bandwidth quality factor (σe×FWHM) can be improved with the introducing of high phonon energy oxide. The results provide practical significance to obtain the excellent spectroscopic glass host applied for the Er3+-doped fiber amplifier (EDFA).
