Persistent luminescence phosphors (PLPs) are largely used in biomedical areas owing to their unique advantages in reducing the autofluorescence and light-scattering interference from tissues. Moreover, PLPs with long-lived luminescence in the near-infrared (NIR) region are able to be applied in deep-tissue bioimaging or therapy due to the reduced light absorption of tissues in NIR region. Because of their abundant election levels and energy transfer channels, lanthanides are widely doped in PLPs for the generation of NIR persistent emissions. In addition, the crystal defects introduced by lanthanides-doping can serves as charge traps in PLPs, which contributes to the enhancement of persistent luminescence intensity and the increase of persistent time. In this paper, the research progress in the synthesis and biomedical applications of lanthanides-doped PLPs with NIR emissions are systematically summarized, which can provide instructions for the design and applications of PLPs in the future.

Co Doped

Cr3+/Ni2+ co-doped optically transparent magnesium aluminosilicate glass-ceramics containing MgAl2O4 nanocrystals have been prepared by heat-treatment. Greatly enhanced broadband near-infrared emission centered at 1216 nm in Cr3+/Ni2+ co-doped glass ceramics is observed when compared with the Ni2+ single-doped glass ceramics under 532 nm excitation. The observed enhancement of infrared emission is attributed to the energy transfer from Cr3+ to Ni2+ ions in the nanocrystalline phase, which leads to the emission due to 3T2(3F) → 3A2(3F) transition of octahedral Ni2+ ions.

By utilizing efficient persistent energy transfer from Ce3+ to Er3+, we have successfully developed a novel garnet persistent phosphor of Y3Al2Ga3O12 doped with Er3+, Ce3+, Cr3+ ions (YAGG:Er–Ce–Cr) exhibiting long (>10 h) near-infrared (NIR) persistent luminescence (PersL) in the broad range from 1450 nm to 1670 nm due to the typical Er3+:4I13/2 → 4I15/2 transition in garnet.
