Highly efficient Fe3+-doped A2BB′O6(A = Sr+,Ca2+;B,B′ = In3+,Sb5+,Sn4+)broadband near-infrared-emitting phosphors for spectroscopic analysis
文献摘要：
Near-infrared(NIR)-emitting phosphor-converted light-emitting diodes have attracted widespread attention in various applications based on NIR spectroscopy.Except for typical Cr3+-activated NIR-emitting phosphors,next-generation Cr3+-free NIR-emitting phosphors with high efficiency and tunable optical properties are highly desired to enrich the types of NIR luminescent materials for different application fields.Here,we report the Fe3+-activated Sr2-yCay(InSb)1-zSn2zO6 phosphors that exhibit unprecedented long-wavelength NIR emission.The overall emission tuning from 885 to 1005 nm with broadened full-width at half maximum from 108 to 146 nm was realized through a crystallographic site engineering strategy.The NIR emission was significantly enhanced after complete Ca2+incorporation owing to the substitution-induced lower symmetry of the Fe3+sites.The Ca2InSbO6∶Fe3+phosphor peaking at 935 nm showed an ultra-high internal quantum efficiency of 87％.The as-synthesized emission-tunable phosphors demonstrated great potential for NIR spectroscopy detection.This work initiates the development of efficient Fe3+-activated broadband NIR-emitting phosphors and opens up a new avenue for designing NIR-emitting phosphor materials.
