Enhancement of Optical Telecommunication Bands: Pr-Doped Halide Phosphate Glasses Display Broadband NIR Photoluminescence Emission.

In the optical energy gap, visible and near-IR emission of halide phosphate glasses with a composition of 40PO-30ZnO-20LiCl-10BaF in mol% doped with 3.5 × 10 ppm PrO, referred to as PZLBPr, were synthesized. The UV-VIS-NIR and spectroscopic properties of these glasses were also predicted.
