Given the escalating significance of near-infrared (NIR) spectroscopy across industries, agriculture, and various domains, there is an imminent need to address development a novel generation intelligent NIR light sources. Here, series Cr3+-doped BaLaMgNbO6 (BLMN) ultrabroadband phosphor with coverage range 650–1300 nm were developed. The emission peak locates at 830 full width half maximum 210 nm. This originates from 4T2→4A2 transition Cr3+ simultaneous occupation [MgO6] [NbO6] octahedral sites confirmed by low photoluminescence spectra (77–250 K), time-resolved spectra, electron paramagnetic resonance spectra. fluxing strategy improves luminescence intensity thermal stability BLMN:0.02Cr3+ phosphors. internal quantum efficiency (IQE) 51%, external (EQE) can reach 33%, be maintained 60%@100 °C. Finally, we successfully demonstrated application BLMN:Cr3+ in qualitative analysis organic matter food freshness detection.

Abstract In this work, the high‐efficiency broadband garnet‐structured NIR phosphor, CaMg 2 Sc Ge 3 O 12 :Cr 3+ (CMSGO:Cr ), has been synthesized using a high‐temperature solid‐phase method. Under 455 nm excitation, CMSGO:Cr exhibits red to near‐infrared (NIR) emission with an ultra‐broad range of 600–1400 and maximum full width at half (FWHM) 273 nm. The Cr ions are found occupy dodecahedral octahedral sites in CMSGO, demonstrating good thermal stability 375 K maintaining 72% that room temperature. phosphor‐converted light emitting diode (pc‐LED) combining phosphor 460 chip excellent optical performance, output power 80 mW@400 mA, photoelectric conversion efficiency 15.69%@20 mA. Furthermore, vein hand, palm, fingers, wrist can be clearly observed under pc‐LED device from phosphor. food testing such as fish fruit is operated night vision improved obviously. All results demonstrate candidate for rapid medical examination imaging, non‐destructive testing, vision.
