Abstract The near‐infrared (NIR) persistent luminescence (PersL) materials have attracted widespread attention owing to the unique self‐sustained light with good penetrability. Currently, most of reported NIR PersL are activated by Cr 3+ . Considering potential toxicity chromium ions, there is an urgent requirement explore ‐free phosphors. Herein, a novel phosphor Sr 2 LuSbO 6 :Fe (SLSO:Fe ) prepared and its properties systematically studied. Fe ‐activated exhibits long‐wavelength emission band centered at 890 nm 110 full‐width half maximum (FWHM), can last over 18 h. shows excellent stability even after being dispersed in solutions different environments for 7 days. Furthermore, emitted penetrate cm thickness beef, evidencing penetration property. This work provides based on technological applications also contributes accelerate development new‐generation ‐doped toward versatile applications.

Broadband near-infrared (NIR) phosphors are crucial components of NIR phosphor-converted light-emitting diode (pc-LED) sources for various smart spectroscopy applications. However, developing an efficient, tunable, and inexpensive broadband phosphor with sufficient spectral coverage remains a great challenge. In this work, cubic phosphate K2AlTi(PO4)3 highly structural rigidity was chosen as host material Cr3+ substitution to create efficient emission. Synthesizing compound, the obtained exhibits emission covering 700–1200 nm peak wavelength ranging from 820 860 depending on substituting concentration. The concentration optimized sample possesses photoluminescence quantum yield (PLQY) 76.4% centered at 857 full width half-maximum (fwhm) 184 under 464 exaction, demonstrating relatively long-wavelength wide coverage. This is mainly derived single kind center deduced analysis, luminescence dynamics, first-principle calculations. Using material, fabricated pc-LED device presents excellent output power photoelectric conversion efficiency, making attractive in practical applications night-vision bioimaging. Therefore, work not only provides superiorities low cost, high wide-range tunability, coverage, but also highlights some clues discover materials.
