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.
