摘要

This study examines the spectral and luminescent properties of zinc phosphate glasses in the ZnO–P2O5 (PZ) system, doped with 0.25 – 1.00 mol.% Er2O3. An increase in the Er2O3 content results in an intensification of the luminescence band centered at approximately 1537 nm. We evaluated the phenomenological Judd–Ofelt intensity parameters (Ωt, where t = 2, 4, 6) and calculated the corresponding radiative transition probabilities, branching ratios, stimulated emission cross sections, and radiative lifetimes of the excited state. The obtained results demonstrate the potential of the studied material as an active medium for near-infrared (NIR) emission.
