Long-wavelength near-infrared light emitting Ni2+-doped double perovskite molybdate-based solid-solution phosphors† Long wavelength near-infrared (LWNIR) light (1000–2000 nm) has great potential in the field of biomedical imaging, non-visual illumination, and non-destructive detection. However, currently, such as Cr3+ and Ni2+ can achieve broadband NIR emission, but their emission wavelengths are under 1600 nm with limited tunability.

High performance NIR-I to NIR-II emission of a Cr3+-doped Cs2NaLuCl6 phosphor with an IQE and EQE of up to 92.9% and 60.75%† Presently, there is a need to expand the near-infrared (NIR) emission range, especially in the bio-transparent window, to improve the internal quantum efficiency and external quantum efficiency, and to minimize the shortcomings of luminescence properties.
