In the current study, Er3+-doped fluorotellurite glasses modified by GaF3 have been developed. High thermal stability and relatively low phonon energy are confirmed by differential thermal analysis and Raman spectroscopy, respectively. Upon 980 nm excitation, intense luminescence emission around 2.71 μm from the Er3+:4I11/2 → 4I13/2 transition is observed in the glass. Based on the Judd-Ofelt theory,...
The Dy3+/Yb3+ co-doped germanate glasses with good thermal stability have been prepared by the conventional melt quenching method. The J-O intensity parameters and radiative properties such as spontaneous transition probilities (Arad), fluorescence branching ratios (β) and radiative lifetimes (τrad) were investigated according to the absorption spectrum based on Judd-Ofelt theory. An intense emission...
