Persistent luminescence nanoparticles (PLNPs) refer to a series of luminescent nanomaterials that can swiftly store the excitation energy and emit persistently after ceasing the excitation. Due to the characteristics of quickly storing the excitation energy and slowly emitting luminescence for a long time after ceasing excitation, they can effectively diminish background fluorescence, and are ideal for fluorescent analysis, especially in autofluorescencefree biosensing and bioimaging.
