Explore Broadband Near-Infrared Phosphor-Perovskite LaLuO 3 :Cr 3+
2021
In this work, a novel near-infrared (NIR) phosphor, LaLuO 3 :Cr3+(LLO:Cr3+), was synthesized by solid state sintered technology in reducing atmosphere. Under 460 nm excitation, LLO:0.01 Cr3+shows broadband NIR emissions between 700 nm and 1200 nm with peaking at ~880 nm. A full width at half maximum (FWHM) and a quantum yield (QY) of the phosphor is about ~160 nm and ~26.5%, respectively.
