Abstract ： Er3+ -doped TeO2 -WO3 -ZnO glasses were prepared and the absorption spectra, emission spectra and fluorescence lifetimes were measured. With more TeO2 content in the glasses, the emission full width at half maximum (FWHM) increases while the lifetime of the 4 I13/2 level of Er3+ decreases. The stimulated emission cross-section of Er3+ calculated by the McCumber theory is as large as 0.86 pm2 . The product of the FWHM and the emission cross-section σe of Er3+ in TeO2 -WO3 -ZnO glass is larger than those in other glasses, which indicates that the glasses are promising candidates for Er3+ -doped broadband amplifiers. The Judd-Offelt parameter Ω6 shows close composition dependence of the 1.5 μm emission bandwidth. The more the TeO2 content is, the larger the values of Ω6 and FWHM.
