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.

“…However, surprisingly, at the LED operating temperature (145 1C), the emission intensity is still controlled at 97.16% compared to room temperature. This result is better than for the Eu 3+ -doped double perovskite phosphors that were recently reported, [43][44][45][46][47] indicating their wonderful thermal stability and outstanding potential for applications in the WLED field. This abnormal thermal quenching behavior has been reported in other work.…”

“…Under the same doping content of 5 mol% RE 3+ , the V of the CITO:0.05Pr 3+ /0.003Mn 4+ phosphor is a little larger than that of the CITO:0.05Sm 3+ /0.003Mn 4+ phosphor, which is well consistent with the previous results that the radius of Pr 3+ is larger than that of Sm 3+ . Besides, the structural distortion (t) of the luminescent activators co-doped samples in double-perovskite materials can be evaluated as below [41,42]…”

Novel rare-earth (Eu 3+ , Sm 3+ , and Pr 3+ ) and transition metal (Mn 4+ ) ions single/co-doped double-perovskite Ca2InTaO6 (CITO) phosphors were prepared and investigated with respect to their crystal structure and photoluminescence (PL) properties. Among them, CITO:Eu 3+ phosphors were found to exhibit an ultra-high internal PL quantum yield (89.1%) and good thermal stability (78.7% at 423 K relative to the initial value at 303 K). As such, the corresponding packaged white lighting-emitting diode (LED) was able to display a remarkable color rendering index (color rendering index = 91.51@10 mA). Besides, the potential in the application of anti-counterfeiting fields and a novel LED structure based on flexible phosphor-converted films were also studied. Moreover, due to their different thermal quenching, trivalent lanthanide (Ln 3+ )/Mn 4+ co-doped CITO phosphors were designed for optical thermometry based on the luminescence intensity ratio (LIR) between different 4f transitions of various Ln 3+ ions and 2 Eg → 4 A2g (Mn 4+ ) transition.Particularly, the LIR between the 4 G5/2 → 6 H9/2 and 2 Eg → 4 A2g peaks of the CITO activated with 5 mol% Sm 3+ and 0.3 mol% Mn 4+ exhibited the most excellent relative sensing sensitivity (3.80% K -1 ) with a beneficial temperature uncertainty of 0.0648 K.Overall, these results are of significance to offer valuable databases for constructing multifunctional high-performance optical platforms using single/co-doped double-perovskite tantalates.
