Near-infrared (NIR) light allows fast and nondestructive detection with deep penetration into biological tissues is widely used in food inspection, biomedical imaging, night vision security, other fields. Cr3+-doped NIR first region (NIR-I) phosphors have many interesting features that attracted a lot of attention recently. However, practical issues, such as low photoluminescence quantum efficiency poor thermal stability, need to be addressed. We synthesized Lu2SrAl4SiO12 garnet-type using high-temperature solid-state reaction method. Under blue-light (@ 430 nm) excitation, the exhibited broadband NIR-I emission range 600–1000 nm, an peak at 710 nm. This system unique, had multipeak sharp-line superposition Cr3+ ions were situated relatively strong crystal field environment, opposed weak environment for matrix. The optimal doping content was 2 mol %, its internal ∼76.8%. Surprisingly, this phosphor showed antithermal quenching effect, integrated luminescence intensity measured 573 K 206.3% 303 K. found caused by extremely expansion coefficient rigid structure matrix temperature range, well weakening electron–phonon coupling increasing temperature. optimized packaged blue chip phosphor-converted light-emitting diode device. source device output power 119.02 mW electro-optical conversion 11.02% under driving current 300 mA. application potential demonstrated high-resolution imaging.
