“…The strategy is to cover NIR phosphors on the most efficient blue chip based on the reference with high recognition and reliability, and achieve the broadband NIR emission through blue chip excitation. The advantages of this scheme are illustrated through its stable structure, wide emission, high efficiency, and low price. , Therefore, a broad NIR-emitting phosphor which can respond in the blue light range is the focus of research. Actually, there are many materials with broadband NIR emission, but broad NIR emission phosphors based on blue chip excitation are rare.…”

The wearable biosensing and food safety monitoring equipment requires high-brightness and thermally stable nearinfrared (NIR) phosphor-converted light emitting diodes (pc-LEDs), and the performance of these pc-LEDs is highly dependent on the properties of the NIR phosphors. This work reports an ultrawide near-infrared emission phosphor Ca 3 Sc 2 Si 3 O 12 : Cr 3+ . Under 460 nm excitation, Ca 3 Sc 2 Si 3 O 12 : Cr 3+ presents an ultrawide emission range from 650 to 900 nm. The weak absorption capacity of Cr 3+ is the main factor causing its undesirable luminous efficiency. Ce 3+ was introduced into the matrix as a role of sensitizer to contribute to the improvement of the absorption of Cr 3+ . An efficient process for energy transfer from Ce 3+ to Cr 3+ can be observed within the Ca 3 Sc 2 Si 3 O 12 codoped substance with Ce 3+ and Cr 3+ . The sample with the best doping concentration has demonstrated excellent thermal stability. At a particular temperature at 150 °C, the phenomenon of the near-infrared emission intensity is maintained at 82% at room temperature. The output power of the NIR-pc-LED based on the Ca 3 Sc 2 Si 3 O 12 : Ce 3+ , Cr 3+ and 450 nm chip reached 21.65 mW@350 mA. The excellent performance of penetrating human tissues demonstrated by the near-infrared pc-LED was observed.
