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.

Abstract Near‐infrared (NIR) phosphors that exhibit high quantum efficiency and excellent thermostability are of critical importance for the development NIR light‐emitting diodes (LEDs) with substantial output power. In this work, Cr 3+ ‐Ni 2+ codoping Y 3 Ga 5 O 12 (YGAO) a internal (IQE), external (EQE), notable thermal stability prepared via solid‐state reactions. When excited by blue light at 437 nm, YGAO:Cr /Ni demonstrate broad intense emission spanning 600–1100 nm 1200–1650 nm. YGAO:3%Cr /0.01%Ni an IQE 96.9% EQE 37.5%, whereas YGAO:6%Cr have 76.2% 36.3%. The luminescence intensities ions 423 K show zero quenching in compared to those 303 K, which is attributed enhancement effect caused electron population between energy levels trap‐supplemented luminescence. LED based on has maximum power 197.79 mW under 1000 mA operating current. Furthermore, also promising potential detection functional groups, night vision, penetration.
