Abstract Developing tunable broadband near‐infrared (NIR) fluorescent materials with outstanding luminescence properties and superior thermal robustness remains a significant challenge for next‐generation intelligent NIR light sources. Herein, high‐performance large‐scale NIR‐emitting garnet‐type phosphor, SrLu 2 Al 3 ScSiO 12 :Cr 3+ (SLASSO:Cr ), is presented. Upon 450 nm blue excitation, SLASSO:1%Cr phosphor yields emission full width at half maximum of 108 prominent sharp peak 694 superimposed on radiation, which attributed to the co‐occupation Cr ions dominant [AlO 6 ] octahedral site (Cr1 site) subordinate [ScO (Cr2 site). Remarkably, as ⁺ content increases, red‐shift in wavelength spanning from 785 bandwidth broadening 89 152 are observed, stems weakening crystal field strength energy redistribution within Cr1 Cr2 centers regulated by formation local ‐Cr ion pairs. Notably, optimal sample boasts an excellent internal quantum efficiency 89.4% exceptional stability (97.6%@423 K). Additionally, fabricated phosphor‐converted light‐emitting diode devices demonstrate promising multi‐functional applications, including plant cultivation, night vision, bioimaging non‐destructive detection.
