Abstract Achieving emission peaks in the near‐infrared II regions (NIR II) and tunable (NIR) is still a huge challenge development of NIR phosphors. Here, series LiSc 1‐y Ga y W 2 O 8 :Cr 3+ phosphors are reported based on crystal engineering, whose luminescence can be tuned from NIR‐II to I. LiScW possesses an ultra‐wide range 850–1400 nm with peak at 1069 full width half maximum (FWHM) 225 main light located region. Introducing into form , spectrum blueshifted, which better aligns characteristic absorption lines most functional groups. Additionally, intensity thermal stability also improved. The phosphor‐converted light‐emitting diodes (pc‐LED) device prepared by using optimized 0.5 :0.12Cr phosphor green chip, different absorptions detected measuring water ethanol pc‐LED as radiation source. These results indicate that :xCr holds potential for applications non‐destructive analysis.

Structural phase evolution is among the most powerful tools for tuning material properties, enabling advancements in catalysis, dielectrics, optoelectronics, and photoluminescence. Such an can significantly enhance near-infrared (NIR) emission properties of Cr3+-doped phosphors. Herein, we present, to best our knowledge, first observation lithiation-induced continuous structural ZnTa2O6 phosphors, driven by Li+ incorporation. This proceeds systematically from orthorhombic (Pbcn) tetragonal (P42/mnm) ultimately trigonal (Li0.5Zn0.5)TaO3 (R3c) as content increases. When doped with Cr3+, NIR peak exhibits a progressive blue shift, moving 949 885 nm eventually 862 nm, tandem evolution. also yields significant enhancements photoluminescent intensity, internal quantum yield (IQY), photoluminescence thermal stability. Our findings establish new paradigm designing highly efficient ultra-broadband phosphors offer foundation developing tantalate-based materials versatile functionalities, including improved dielectric properties.
