Efficient Short-Wave NIR Emission Induced by Energy Transfer from Cr3+ Clusters to Ni2+ in LiAl5O8: Cr3+, Ni2+ Phosphor-in-Glass for Spectroscopy Applications

To achieve efficient Short-wave infrared (SWIR) light sources, a series of LiAl5O8: Cr3+, Ni2+ phosphors were synthesized, demonstrating excellent internal quantum efficiency (IQE = 94.56%) and thermal stability (I423K/I293K =...
