Explore Broadband Near-Infrared Phosphor-Perovskite LaLuO3:Cr3+

Abstract

In this work, a novel near-infrared (NIR) phosphor, LaLuO3: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.
