Shortwave infrared (SWIR)-emitting materials have emerged as superior light sources with increasing demand for potential applications in noninvasive analysis, night vision illumination, and medical diagnosis. For developing next-generation SWIR phosphor-converted light-emitting diodes (pc-LEDs), the scarcity of intense blue-light-pumped broadband luminescent poor thermal stability current Ni2+-activated phosphors are ongoing challenges. Here, a blue-light-excitable (440 nm) Y3Al2Ga3O12:Cr3+,Ni2+ phosphor ultrawide emission centered at ∼1430 nm (FWHM ∼264 is reported. The efficient Cr3+ → Ni2+ energy transfer exploited remarkable enhancement 18-fold under blue-light excitation. Significantly, excellent (90% 440 K) band obtained codoped which best among reported phosphors. Besides, experimental techniques (XANES EXAFS) density functional theory calculations employed to investigate local structure propose [GaO6] octahedrons favorable occupation sites Ni2+/Cr3+ ions.

Developing efficient and stable near-infrared emitters related to Cr3+-pairs for advanced optoelectronic devices remains a challenge due concentration quenching effects unclear luminescence mechanisms. In this study, Cr3+ ions are incorporated into matrix structure consisting of ZnAl₂O₄ spinel units separated by 11.312 Å, effectively restricting energy transfer between luminescent centers alleviating effects. Computational analysis identifies the lattice positions isolated at different doping levels, providing insights their spatial distribution local structural environments. Photoluminescence measurements reveals Cr3+-concentration-dependent emission broadening, with Cr3+-pair band peak 750 nm, while detailed spectral further clarified level first time. Enhanced material performance is achieved through flux-assisted synthesis, reaching high external quantum efficiency 58.3%. Consequently, assembled pc-LEDs exhibit minimal roll-off achieve output 183 mW 650 mA, demonstrating potential in light sources night vision technology application.

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.
