Broadband near-IR photoluminescence in Ni2+ doped gallium silicate glass–ceramics

Ligand field design enables quantum manipulation of spins in Ni2+ complexes

“…57,80,83,84 This value is 66% of the free-ion value (1030 cm −1 ), 83 and signicantly smaller in comparison to other Ni 2+ complexes, including [Ni(tacn) 2 ] 2+ (B solution = 993 cm −1 and B single crystal = 840 cm −1 ). 81,[85][86][87][88][89] The electronic absorption spectroscopy data demonstrates that the thioether ligand provides a strong ligand eld around the nickel ion and leads to a reduction in the interelectronic repulsion parameter, B.…”
