Abstract Long‐wavelength near‐infrared (NIR) phosphors (1000–2000 nm) have shown great promise in intelligent NIR spectroscopy technology fields. However, developing capable of directly absorbing blue light and emitting over 1000 nm still remains a significant challenge. Here, series ultra‐broadband with emission peaks longer than 1500 is achieved by incorporating single activator Ni 2+ ion into ALaMgMO 6 (A = Ca, Sr, Ba; M Sb, Nb, Ta) double perovskite hosts. Significantly, through composition modulation strategy, the designed exhibit an intense absorption band centered at 440 nm, making these mono‐doped pumped commercial LED chips without strictly introducing sensitized ions or energy transfer process. The origination effective blue‐light excitable NIR‐II to NIR‐III phosphor unraveled Rietveld structural refinement local symmetry analysis. Additionally, developed demonstrated potential spectroscopic analysis, night‐vision technology, non‐destructive visualization, information encryption identification. This work provides feasible strategy solve problem that ‐doped cannot be can promote development more long‐wavelength materials for multiple photonic applications.
