Abstract

Persistent luminescence (PersL) in Eu3+-doped ZrO2 was investigated as a potential alternative approach for radiation dosimetry under beta-particle irradiation. ZrO2:Eu3+ powders with different dopant concentrations were synthesized by solid-state reaction and structurally characterized by powder X-ray diffraction, confirming the formation of monoclinic ZrO2 and effective Eu3+ incorporation. TL and PersL measurements reveal the presence of shallow trapping centers, mainly associated with a low-temperature TL glow peak at 61 °C, which are responsible for the PersL emission. The sample doped with 5 mol% Eu3+ exhibits enhanced PersL intensity, a nearly linear dose–response in the range of 0.078 to 23.4 Gy, and improved repeatability over multiple irradiation–readout cycles. These results demonstrate that ZrO2:Eu3+ is a promising candidate for persistent luminescence-based radiation dosimetry.
