Abstract The persistent luminescence (PersL) induced by X‐rays in fluoride materials has garnered widespread application within the field of optoelectronics. However, complexity trap systems multi‐component impeded further exploration into PersL properties. Here, a compound consisting solely and lanthanide ions is focused on, which simplifies revelation mechanism under X‐ray excitation. Experimental theoretical results reveal that phenomenon primarily attributed to migration recovery processes interstitial lattice. Depending on localization ions, corresponding Frenkel defects can be classified two distinct types: those are readily self‐recoverable near matrix less likely self‐recover dopant ions. anomalous phenomena observed at temperatures do not correspond thermoluminescence spectra substantiate existence these dynamic traps. Furthermore, leveraging material's superior properties, scintillator film prepared utilized for imaging static displays. These findings provide refined understanding related defects, laying solid foundation continued development technology.

Persistent luminescence phosphors (PLPs) can remain luminescent after excitation ceases and have been widely explored in bioimaging therapy since 2007. In bioimaging, PLPs efficiently avoid tissue autofluorescence light scattering interference by collecting persistent signals the end of excitation. Outstanding signal-to-background ratios, high sensitivity, resolution achieved with PLPs. therapy, continuously produce therapeutic molecules such as reactive oxygen species removing sources, which realizes sustained activity a single dose stimulation. However, most are activated ultraviolet or visible light, makes it difficult to reactivate vivo, particularly deep tissues. recent years, sources penetration activate PLPs, including X-ray, γ-ray, ultrasound. Researchers found that various inorganic organic be ultrasound, making these valuable imaging deep-seated tumors.
