Here, we apply frequency-domain analysis to persistent luminescence (PersL) materials, which exhibit long-lasting emission following excitation due to charge trapping and detrapping processes spanning wide temporal ranges. Using SrAl₂O₄:Eu²⁺,Dy³⁺ (SAO:Eu,Dy) as a model system, we develop a general framework for frequency-domain characterization of PersL and report, for the first time, a direct measurement of the trapping rate in such a material. Our approach also enables quantitative assessment of trapping probability, efficiency, and overall PersL performance. This work opens a new pathway for rational optimization of afterglow materials based on mechanistic insights beyond conventional time-domain approaches.This project has received funding from the BBVA Foundation Leonardo Grant for Physics Researchers 2023, and from MCIN/AEI/10.13039/501100011033 by European Union NextGeneration EU/PRTR under grant EUR2023-143467 and PID2024-161708OB-I00.
