摘要：

Near infrared (NIR) phosphors have a wide emission range, high quantum yield and good absorption efficiency, which can meet the detection needs of different wavelengths in the NIR spectrum, exhibiting great developmental potential. In this study, a novel near-infrared phosphor Li1.6Mg1.6Sn2.8O8:Cr3+ (referred to as LMSO:Cr3+) has been developed, with a near-infrared emission wide-band from 600 to 1200 nm, a peak at 860 nm, and a full width at half maximum of 187 nm. It possesses an internal quantum efficiency of 51.6% and a high absorption efficiency of 59%, leading to an external quantum efficiency of 30.7%. A NIR pc-LED device prepared using this material can achieve a high NIR output power of 25.20 mW at a driving current of 100 mA and a photoconversion efficiency of 14.71% at a driving current of 10 mA, exhibiting excellent performance in near-infrared spectroscopic detection, penetration of biological tissues, and night vision imaging.
