“…Trapping levels play an important role in PLMs, − the excited electrons can be captured by traps via nonradiative relaxation, and slowly released electrons from traps cause persistent luminescence after irradiation was removed. Figure shows the thermoluminescence (TL) curves at different contents of Si 4+ in ZGSiO:Cr.…”

Persistent luminescence nanoparticles (PLNPs) can provide long afterglow after excitation and possess advantages for advanced optical anticounterfeiting. Nevertheless, PLNPs with dual-wavelength persistence luminescence for dynamic and multimode anticounterfeiting are just at the initial stages. Herein, we synthesized dual-wavelength (503 and 696 nm) afterglow PLNPs Zn 0.2 Ga 1.1 Si 0.9 O 3.65 :Cr (ZGSiO:Cr) using a hydrothermal method followed by calcination. The luminescence color and the afterglow time of PLNPs are tunable through the content of Si 4+ . The colors of the emission, including red, white, cyan, and purple, could be observed under single ultraviolet (UV)-light irradiation; the PLNPs show the visible afterglow emission, after UV-light irradiation. The as-prepared ZGSiO:Cr exhibits high-level, dynamic, and multimodal anticounterfeiting with facile and quick operation and low cost and provides a more convenient and effective method for multimode anticounterfeiting, encryption, and currency information tracking.
