Cr3+/Er3+ co-doped LaAlO3 perovskite phosphor: a near-infrared persistent luminescence probe covering the first and third biological windows

We have developed a novel persistent phosphor of LaAlO3 perovskite doped with Er3+, Cr3+ and Sm3+ (LAO:Er-Cr-Sm), which exhibits long persistent luminescence (PersL) at 1553 nm due to the Er3+:4I13/2 [rightward arrow] 4I15/2 transition as well as at 734 nm due to the Cr3+:2E(2G) [rightward arrow] 4A2(4F) transition.
