Abstract:: Persistent luminescence nanoparticles (PLNPs) are special luminescent materials with long afterglow time. In particular, rare earth elements (REE) doped PLNPs (REE-PLNPs) possess unique 4f electron configuration, excellent physical and chemical stability, high luminescence intensity, quantum yield, and long afterglow time. The emission wavelength range of REE-PLNPs can be changed by adjusting REE ion species and doping element concentration.Although the luminescence centers are the same, different PLNPs matrix materials often have different optical properties due to the different lattices to which the different materials belong. Therefore, the luminescence intensity of REE-PLNPs can be improved by changing the type of matrix materials and rare earth co-doped ions, and then the afterglow performance can be optimized. Therefore, REEPLNPs has attracted the attention of researchers in the fields of interior decoration, safety sign, instrument display, biological detection and imaging, and integration of diagnosis and treatment.The composition and afterglow luminescence properties of REE-PLNPs, including lanthanide elements and Sc and Y, are reviewed. The advantages of REE in improving the emission wavelength and afterglow intensity of PLNPs are also reviewed, and the future development direction of REE-PLNPs research is prospected.
