Persistent luminescence is a process where the material emits light in the visible range appreciably for hours even after the irradiation source has been waived off. The storage of the irradiation energy by the traps is supposed to be responsible for long decay time of persistence luminescence.
However, up-conversion luminescence relies strictly on high power coherent excitation, e.g., laser sources, and the NIR laser may create a heating effect at high input laser power. Persistent luminescent materials or phosphors feature long-lasting emission up to several days after the removal of the excitation sources (usually UV and X …
