摘要 | Near-infrared (NIR) phosphor-converted light-emitting diodes (pc-LEDs) are an emerging light source demanded for the miniaturization of NIR spectroscopy. However, the photoelectric efficiency and spectral properties of NIR pc-LEDs are still very limited due to a lack of efficient broadband NIR phosphors with peak emission wavelength >850 nm. Here, a novel Cr3+-activated perovskite-like Mg4Ta2O9 phosphor is reported, which exhibits a broad NIR emission band peaking at 850 nm with a high internal (external) quantum efficiency of 72% (33.4%). The fabricated NIR pc-LED shows a broad emission band covering the whole 700-1100 nm spectrum range with a photoelectric conversion efficiency of 22.1% at 10 mA. This work may provide a new paradigm for the discovery of Cr3+ singly doped NIR phosphors with excellent performance. |
