摘要:
Near-infrared (NIR) light sources have important applications in biomedical detection, food inspection, biochemical sensing, night vision, and other fields. Developing a broadband NIR luminescent material with multifunction will help the application and promotion of NIR light sources in various fields. This work designed Cr 3+ to occupy the weaker crystal field sites in the phosphate KInP 2 O 7 (KIPO) lattice for achieving NIR phosphors with a broad emission band. Under 472 nm excitation, KIPO: Cr 3+ exhibits NIR broadband emission centering ∼...
