摘要：
The Er3+-doped TeO2-WO3-ZnO-ZnF2(TWZOF) glasses were prepared. The absorption spectra, 1.5 mum emission spectra and fluorescence lifetimes of Er3+, excited at 970 nm, were measured. The J-O parameters Omega(t) (t = 2, 4, 6), absorption and emission cross-sections were calculated. The dependence of the 1.5 km emission intensity, fluorescence lifetime and bandwidth of the Er3+ emission upon the contents of ZnF2 in glass were investigated. In TWZOF glass, Er3+, ions had a broad emission profile around 1.5 mum with the maximum FWHM of 83 nm. With the increasing of the content Of ZnF2, the emission intensity at peak wavelength and the fluorescence lifetime of Er3+ at 1.5 mum increase.
