Description
Summary:Nd3+-doped mixed-anion fluoro-sulfo-phosphate (FPS) glass has been investigated as a laser material in detail. It is found that anion-mixing in Al(PO3)3-BaF2-BaSO4 glass system enables excellent physical properties and chemical durability. Besides, the complicated local environment provided by multi-component leads to high radiative transition probability and influences other luminescent properties considerably. The measured lifetime of Nd3+: 4F3/2 in FPS is 349.8 μs and the quantum efficiency is 92.91%, higher than those of phosphate and fluoro-phosphate glasses. These results suggest that the FPS glass system could be a promising candidate for 1.06 μm laser source. •Nd3+-doped fluoro-sulfo-phosphate glass systems were investigated.•Glass-forming regions of the glasses were predicted via the thermodynamic method.•Optical and spectroscopic properties of the FPS glass were investigated.
