英文摘要	er3+- doped fluorozirconate (zrf4-baf2-yf3-alf3) and oxyfluoroaluminate glasses are successfully prepared here. these glasses exhibit significant superiority compared with traditional fluorozirconate glass (zrf4-baf2-laf3-alf3-naf) because of their higher temperature of glass transition and better resistance to water corrosion. judd-ofelt (j-o) intensity parameters are evaluated and used to compute the radiative properties based on the vis-nir absorption spectra. broad emission bands located at 1535 and 2708 nm are observed, and large calculated emission sections are obtained. the intensity of 2708 nm emission closely relates to the phonon energy of host glass. a lower phonon energy leads to a more intensive 2708 nm emission. the energy transfer processes of er3+ ions are discussed and lifetime of er3+: i-4(13/2) is measured. it is the first time to observe that a longer lifetime of the 4i13/2 level leads to a less intensive 1535 nm emission, because the lifetime is long enough to generate excited state absorption (esa) and energy transfer (et) processes. these results indicate that the novel glasses possess better chemical and thermal properties as well as excellent optical properties compared with zblan glass. these er3+-doped zbya and oxyfluoroaluminate glasses have potential applications as laser materials.
