Divalent Nickel-Activated Gallate-Based Persistent Phosphors in the Short-Wave Infrared

Divalent Nickel-Activated Gallate-Based Persistent Phosphors in the Short-Wave Infrared

Short‐wave infrared (SWIR, 900–1700 nm) persistent phosphors are developed by doping Ni2+ ions into gallate‐based hosts including zinc gallogermanates, lithium gallates, and lanthanum gallogermanates. These SWIR persistent phosphors exhibit single‐band persistent luminescence in the range of 1000–16...

Zusammenfassung:Short‐wave infrared (SWIR, 900–1700 nm) persistent phosphors are developed by doping Ni2+ ions into gallate‐based hosts including zinc gallogermanates, lithium gallates, and lanthanum gallogermanates. These SWIR persistent phosphors exhibit single‐band persistent luminescence in the range of 1000–1600 nm. SWIR persistent luminescence lasting for hours is demonstrated in the Zn3Ga2Ge2O10:Ni2+ phosphor.
