A series of thulium-doped gallium-rich germano-gallate glasses are fabricated and
thoroughly investigated. Their synthesis under an atmosphere-controlled glove box allows …

Abstract Er3+-doped fluorozirconate (ZrF4-BaF2-YF3-AlF3) and oxyfluoroaluminate glasses
are successfully prepared here. These glasses exhibit significant superiority compared with …

A germanate-tellurite glass (GeO2-TeO2-K2O-Nb2O5-La2O3) with thulium do** has been
investigated for application as a laser material around 2.0 μm regions. Under the 808 nm …

Enhanced 2.7 μ m emission is obtained in Er3+/Tm3+ and Er3+/Ho3+ codoped ZBYA
glasses. Absorption and emission spectra are tested to characterize the 2.7 μ m emission …

Two novel Tm 3+-doped silicate glasses (one with fluoride addition) with good thermal
stability were prepared in this work. Luminescence properties of these two samples were …

The fluorescence properties of 2.7 μm emission and energy transfer mechanism of Ho 3+/Er
3+ co-doped fluoride glass (ZBYA) have been investigated in the present paper. Ho 3+ …

Abstract Tm 2 O 3-doped multi-component silicate glasses without alkali ions are prepared
using a conventional melt quenching method. The Judd–Ofelt theory is applied to calculate …

The 2 μm emission spectra and lifetimes of Ho^ 3+ ions in germanate glasses with different
do** concentrations were investigated. The Judd-Ofelt parameters, radiative transition …

The compositional dependence of the 1.8 μm emission properties of Tm 3+ ion-doped lead
silicate glasses is investigated. Judd–Ofelt parameters are calculated and their variation with …

Emissions at 2.7 μm from telluride glasses with various Er 2 O 3 do** concentrations are
investigated. The prepared glasses have excellent thermostability and high rare-earth …
